Safety Instructions

All instructions must be read and observed in order for the measuring tool to function safely. The safeguards integrated into the measuring tool may be compromised if the measuring tool is not used in accordance with these instructions. Never make  warning signs on the measuring tool unrecognizable. SAVE THESE  INSTRUCTIONS FOR FUTURE REFERENCE AND INCLUDE THEM WITH THE MEASURING TOOL WHEN TRANSFERRING IT TO A THIRD PARTY.

• Warning! If operating or adjustment devices other than those specified here are used or other procedures are carried out, this  can lead to dangerous exposure to radiation.
• The measuring tool is delivered with a laser warning sign (marked in the illustration of the measuring tool on the graphics page).
• If the text of the laser warning label is not in your national language, stick the provided warning label in your national language over it before operating for the first time.
  Do not direct the laser beam at persons or animals and do not stare into the direct or reflected laser beam yourself. You could blind somebody, cause accidents or damage your eyes.
• If laser radiation hits your eye, you must close your eyes and immediately turn your head away from the beam.
• Do not make any modifications to the laser equipment.
• Do not use the laser goggles (accessory) as protective goggles. The laser goggles make the laser beam easier to see; they do not protect you against laser radiation.
• Do not use the laser goggles (accessory) as sunglasses or while driving. The laser goggles do not provide full UV protection and impair your ability to see colours.
• Have the measuring tool serviced only by a qualified specialist using only original replacement parts. This will ensure that the safety of the measuring tool is maintained.
• Do not let children use the laser measuring tool unsupervised. They could unintentionally blind themselves or other persons.
• Do not use the measuring tool in explosive atmospheres which contain flammable liquids, gases or dust. Sparks may be produced inside the measuring tool, which can ignite dust or fumes.
• Do not open the battery. There is a risk of short-circuiting.
• In case of damage and improper use of the battery, vapours may be emitted. The battery can set alight or explode. Ensure the area is well  ventilated and seek medical attention should you experience any adverse effects. The vapours may irritate the respiratory system.
• If used incorrectly or if the battery is damaged, flammable liquid may be ejected from the battery. Contact with this liquid should be avoided. If contact accidentally occurs, rinse off  with water. If the liquid comes into contact with your eyes, seek additional medical attention. Liquid ejected from the battery may cause irritation or burns.
• The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit may occur, causing the battery to burn, smoke, explode or overheat.
• When the battery is not in use, keep it away from paper clips, coins, keys, nails, screws or other small metal objects that could make a connection from one terminal to another. A short circuit between the battery terminals may cause burns or a fire.
• Only use the battery with products from the manufacturer. This is the only way in which you can protect the battery against dangerous overload.
• Only charge the batteries using chargers recommended by the manufacturer. A charger that is suitable for one type of battery may pose a fire risk when used with a different battery.
  Protect the battery against heat, e.g. against continuous intense sunlight, fire, dirt, water and moisture. There is a risk of explosion and short-circuiting.
• Remove the rechargeable battery/non-rechargeable batteries from the measuring tool before carrying out work on the measuring tool (e.g. assembly, maintenance, etc.). The battery/batteries should also be removed for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.
• Caution! When using the measuring tool with Bluetooth®, a fault may occur in other devices and systems, aeroplanes and medical devices (e.g. pacemakers, hearing aids). Also, damage to people and animals in the immediate vicinity cannot be completely excluded. Do not use the measuring tool with Bluetooth® in the vicinity of medical devices, petrol stations, chemical plants, areas with a potentially explosive atmosphere and in blasting areas. Do not use the measuring tool with Bluetooth® on aeroplanes. Avoid using the product near your body for extended periods.
  The Bluetooth® word mark and logos are registered trademarks owned by Bluetooth SIG, Inc. and any use of such marks by Robert Bosch Power Tools GmbH is under license.
• Protect the measuring tool, particularly the area around the air humidity, ambient temperature and in frared sensor, from moisture, snow, dust and dirt. The reception lens could fog up or become contaminated and distort the measurements. Incorrect settings on the tool and other atmospheric influences may make the measurements inaccurate. Object temperatures could be shown to be hotter or colder than they are, which may present a danger if touched.
• Correct temperature measurements are only possible if the set emissivity and emissivity of the object agree, and the correct reflected temperature is set. Otherwise, object temperatures could be shown to be hotter or colder than they are, which may present a danger if touched.

Safety Instructions When Using Thermocouples 

• Thermocouples must not be used in live electrical systems. This poses a risk to life!
• Using a thermocouple means contact with the object measured. Therefore, watch out for potential dangers due to temperature, voltage or a chemical reaction.

Product Description and Specifications

Please observe the illustrations at the beginning of this operating manual.

Intended Use

The measuring tool is intended for contactless measurement of surface temperature, ambient temperature and relative humidity. It calculates the dew point temperature and indicates thermal bridges and mould risk. Mould spores cannot be detected with the measuring tool. However, it can help to detect conditions early on that can encourage mould growth.
The measuring tool may not be used to measure the body temperature of humans or animals or for other medical purposes.

The measuring tool is not suitable for measuring the surface temperature of gases.

Temperature measurement in liquids is only possible using a commercially available thermocouple (connection type K), which can be connected to the measuring tool via the interface (25) intended for this.

The light of this measuring tool is intended to illuminate the direct work area of the measuring tool in order to take pictures.

The laser points must not be used as a laser pointer. They are solely for marking out the area being measured. The measuring tool is suitable for indoor and outdoor use.

Assembly

Measuring Tool Power Supply

The measuring tool can be operated either with conventional non-rechargeable batteries or with a Bosch lithium-ion battery.

Article number 3 601 K83 371: The measuring tool can only  be operated using commercially available batteries.

Operation With Non-Rechargeable Batteries (Not With Article Number 3 601 K83 371) (see figure B)
The batteries are inserted into the battery adapter.

• The battery adapter is intended only for use in designated Bosch measuring tools and must not be used with power tools.
  To insert the batteries, slide the receptacle (27) of the battery adapter into the battery bay (29). Place the batteries in the receptacle as shown in the picture on the cap (28). Push the cap over the receptacle until you feel it click into place
  To remove the batteries, press the release buttons (3) on the cap (28) and pull the cap off. Hold the measuring tool with the battery bay (29) facing upwards to ensure that the batteries do not fall out when you do this. Remove the batteries. To remove the receptacle (27) from inside the battery bay, reach into the receptacle and pull it out of the measuring tool, applying light pressure to the side wall as you do so.
  Always replace all the batteries at the same time. Only use batteries from the same manufacturer and which have the same capacity.
• Take the batteries out of the measuring tool when you are not using it for a prolonged period of time. The batteries can corrode and self-discharge during prolonged storage in the measuring tool.

Operation With Rechargeable Battery (Not With Article Number 3 601 K83 371) (see figure C)

Use only the chargers listed in the technical data. Only these chargers are matched to the lithium-ion battery of your measuring tool

Note: The use of batteries unsuitable for your measuring tool can lead to malfunctions or damage to the measuring tool.

Note: The battery is supplied partially charged. To ensure full capacity of the battery, completely charge the battery before the first use. The lithium-ion battery can be charged at any time without reducing its service life. Interrupting the charging process does not damage the battery.

To insert the charged battery pack (30), slide it into the battery bay (29) until you feel it click into place and it is flush with the handle of the measuring tool.
To remove the battery pack (30), press the release buttons (3) and pull the battery pack out of the battery bay (29). Do not use force to do this

Operation With Non-Rechargeable Batteries (3 601 K83 371) (see figure D)

Press the release buttons (3) to open the battery compartment cover (31) and then remove the battery compartment cover

Make sure you insert the batteries the right way round according to the picture on the battery compartment cover. Put the battery compartment cover (31) back on and gently push it until you feel it click into place.

Always replace all the batteries at the same time. Only use batteries from the same manufacturer and which have the same capacity.

• Take the batteries out of the measuring tool when you are not using it for a prolonged period of time. The batteries can corrode and self-discharge during prolonged storage in the measuring tool.

Operation

Starting Operation 

• Protect the measuring tool from moisture and direct sunlight.
• Do not expose the measuring tool to any extreme temperatures or variations in temperature. For example, do not leave it in a car for extended periods of time. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. The precision of the measuring tool may be compromised if exposed to extreme temperatures or variations in temperature.
• Make sure that the measuring tool is correctly acclimatised. In case of large variations in temperature, acclimatisation can take up to 60 minutes. This may be the case, for example, if you store the measuring tool in a cool car and then perform a measurement in a warm building.
• Avoid hard knocks to the measuring tool or dropping it. After severe external influences and in the event of abnormalities in the functionality, you should have the measuring tool checked by an authorised Bosch aftersales service agent.

Switching on/off

Take the protective cap (21) off the infrared reception lens (23) and the protective cap (19) off the humidity and ambient temperature sensor (5). Make sure that the camera (22), reception lens (23) and sensor(5) are not closed or covered when working, as this will affect the accuracy of the measurements taken.

To switch on the measuring tool, press the on/off button (12) or the measure button (4). A start sequence will appear on the display (18). After the start sequence, the measuring tool will be in the operating mode that was saved the last time the tool was switched off. The lasers are not yet switched on.

Only upon the initial starting operation does the Tool menu also appear after the start sequence. In this menu, you can determine the settings of the measuring tool, such as the language of all displays (see Tool submenu”, page 15). Confirm the selected settings by pressing the right-hand function button (10). You can also change any of the settings later in the Tool submenu

• Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use. Others may be dazzled by the laser beam.
• Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a distance).

In the factory setting, the brightness of the display lighting is reduced 30 s after each button press to save energy. Pressing any button will switch the display lighting back to full strength. In the menu, you can change this lighting time.

To switch off the measuring tool, press the on/off button (12). The measuring tool saves the current operating mode and the settings and then switches off. Put the protective cap (21) back on the reception lens (23) and put the protective cap (19) on the humidity and ambient temperature sensor (5).

Do not switch off the measuring tool by removing the battery pack or battery adapter because this may damage the internal memory in certain cases.

In the main menu, you can set whether and after how long without button press/measurement the measuring tool automatically switches off (see “”, page 15). The current operating mode and the settings are also saved when the tool switches off automatically

If the rechargeable battery or the measuring tool are outside the operating temperature specified in the Technical Data, the measuring tool will be switched off automatically after a short warning (see “Errors – causes and corrective measures”, page 16). Allow the measuring tool to reach the correct temperature and then switch it back on.

Measurement preparations

Setting the emissivity for surface temperature measurements

To determine the surface temperature, the tool performs a contactless measurement of the natural infrared thermal radiation emitted by the object at which the tool is aimed. To ensure correct measurement, the emissivity setting on the measuring tool must be checked before every measurement and adapted to the measuring object if necessary. The preset emissivities in the measuring tool are reference values.

You can select one of the preset emissivity levels or enter an exact numerical value. Set the required emissivity via the Measurement> → menu.

• Correct temperature measurements are only possible if the set emissivity and emissivity of the object agree, and the correct reflected temperature is set. Otherwise, object temperatures could be shown to be hotter or colder than they are, which may present a danger if touched.

The lower the emissivity, the greater the effect of the reflected temperature on the measuring result. Always adjust the reflected temperature when changing the emissivity. Set the reflected temperature via the Measurement → <Reflected Temp. > menu.

If there are several objects with a different emissivity being measured within the measured area identified by the laser, the temperature measurement can be distorted.

Measured area for surface temperature measurements
The laser points generated by the measuring tool border the exterior circular measured area. The displayed measured temperature value shows the average surface temperature within this area.

Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a distance)

Increasing the distance between the measuring tool and the object you are measuring will increase the distance between the laser points and consequently the size of the area measured.

If the laser points are difficult to recognise, you can switch on the Measuring Frame (b) on the display (see “”, page 15). The measuring frame can be used to indicate the area being measured and helps to improve orientation. The measuring frame may vary from the area being measured depending on the measuring distance. The area  located between the laser points is decisive for the measurement.

Information about the measuring conditions 

Highly reflective, shiny or transparent surfaces (e.g. highgloss tiles, stainless steel cupboard fronts or saucepans) may impair the surface temperature reading. If necessary, mask the area to be measured with a dark, matt adhesive tape that conducts heat well. Allow the tape to acclimatise briefly on the surface.

It is not technically possible to perform measurements through transparent materials.

Consequently, the more suitable and stable the measuring conditions are, the more accurate and reliable the results of the measurement will be.

The humidity and ambient temperature sensor (5) can be damaged by chemical contaminants, such as paint or varnish vapours. Infrared temperature measurement is impaired by smoke, vapour or dusty air.

It is therefore important to ventilate the room prior to measuring, especially when the air is contaminated or steamy. For example, do not perform measurements in a bathroom immediately after the shower has been used.

Once ventilated, allow the room to reacclimatise a while until it returns to the usual temperature.

The ambient temperature and relative humidity are measured directly on the measuring tool at the humidity and ambient temperature sensor (5). To achieve meaningful results, do not hold the measuring tool directly over or next to sources of interference such as radiators or open liquids. Do not cover the sensor (5) under any circumstances.

Make sure that a favourable measuring angle is used on reflective surfaces in order to ensure that the thermal radiation reflected by other objects does not distort the result. For example, the reflection of your body heat may interfere with the measurement when measuring head-on from a perpendicular position.

Setting the zoom level

For ongoing measurements and when rendering saved screenshots, the image detail on the display can be shown at 3 different zoom levels: 0.5 m, 2 m and 5 m.
The zoom levels are optimised for the corresponding distance between the measuring tool and the object being measured. At a measuring distance of 2 m, the zoom level “2 m” renders the (typically) best image detail.

The indicator for the current zoom level (d) is shown on the display. To increase the zoom level, press the “Zoom in” (up) arrow button (16); to decrease the zoom level, press the “Zoom out” (down) arrow button (13).

Due to the parallax, the measuring frame (b) only corresponds to the measuring range if the selected zoom level corresponds to the actual measuring distance.

Illuminating the area you are measuring

When measuring in dark areas, you can switch on the light (24) to improve the display of the screen content. This can help you to achieve a better result when saving screenshots.

Press the button (14) to switch the light (24) on or off. To save energy, the light switches off automatically when the brightness of the display lighting is reduced. You can change how long the display stays lit in the menu (see “”, page 15). The light is not automatically switched on when the display lighting is switched back on. For energy saving reasons, the light is not available when the battery pack’s state of charge is in the critical range.

Measuring functions

Switching Between Individual Modes 

Select the required mode with the right (11) or left (15) arrow buttons (the mode is displayed with a short explanation). To hide the explanation early, press the save button (9). To hide the explanation and immediately start a measurement, press the measure button (4).

Surface temperature mode 

Surface temperature mode is used to measure the surface temperature of objects.

In this mode, you can, for example, check radiators or look for overheated machine parts.

You start the measurement by pressing the measure button (4). The measured values shown on the display are continuously being updated. As soon as you let go of the measure button (4), the measurement is interrupted and the lasers are switched off. On the display, the last measurement results are fixed on the (n) indicator. The last measured surface temperature is displayed with the marking (p) on the result scale (k).

Once the difference between the measurements taken is more than 3 °C, the minimum and maximum temperatures measured during the process will appear on the display (j). This enables you to tell how high the current measured value is in relation to the temperatures already measured.

Thermal bridge mode 

The measuring tool can support you in detecting thermal bridges (see “Thermal bridge”, page 16). Before measurement can be started, the external temperature must first be set. To do so, open the Main Menu (see “Navigating in the “, page 14). Select the  submenu and set the current external temperature. You start the measurement by pressing the measure button (4).

Taking into account the internal ambient temperature and the external temperature, you can determine whether the surface temperature meets the minimum requirements of the heat shield. If the surface temperature falls below the minimum requirements, a structural defect is assumed and a thermal bridge warning given.

Once the measurement has been taken, the surface temperature of the object you last measured is fixed on the display (n), as is the ambient temperature (h). The calculated fRsi value (see “Thermal bridge”, page 16) and its estimated tolerance are shown on the display   (v).

The measuring tool displays the interpretation of the values with the marking (p) on the result scale (k).

• Marking (p) in the green range (fRsi value over 0.7, including tolerance): No thermal bridge
• Marking (p) in the yellow range (borderline fRsi value of 0.7): A thermal bridge may be in the measuring range. Measurement should be repeated under favourable environmental conditions (e.g. at a lower external temperature).
• Marking (p) in the red range (fRsi value under 0.7, including tolerance): A thermal bridge is probably in the measuring range.

Dew point mode 

The measuring tool can support you in detecting places at risk of damage from mould. The dew point temperature (see “Dew point temperature”, page 17) is calculated from the additionally measured ambient temperature and relative air humidity (see “Relative humidity”, page 17) in this mode. The dew point temperature is compared here with the measured surface temperature and interpreted in terms of the risk of mould formation.

Note that the measuring results always represent only a snapshot based on the current environmental conditions. A forecast for possibly changing environmental conditions cannot be made. If the measurement yields critical results, you should repeat the measurement at different times and under different conditions.

You start the measurement by pressing the measure button (4). The measured values shown on the display are continuously being updated.

Once the measurement has been taken, the surface temperature of the object you last measured is fixed on the display (n), as are the ambient temperature (h) and the relative humidity (g). The calculated dew point temperature is displayed in (i).

The measuring tool automatically helps in the interpretation of the values with the marking (p) on the result scale (k)

• Marking (p) in the green range: There is no risk of mould under the current conditions.
• Marking (p) in the yellow range: The values are borderline; pay attention to the room temperature, thermal bridges and humidity, and repeat the measurement later if necessary.
• Marking (p) in the red range: There is an increased risk of mould because the humidity is too high or the surface temperature is close to the dew point temperature. The respective value flashes in the indicator.

A mould risk warning is given when the surface temperature is 80 % of the dew point temperature.

Note: Mould spores cannot be detected with the measuring tool. It only indicates that mould may form if the conditions remain unchanged.

Contact Temperature Mode 

Contact temperature measurement enables the temperature of an object to be measured directly using a commercially available type K thermocouple.

The contact temperature measurement can be a helpful addition to the contactless temperature measurement. Application is sensible particularly in situations in which the infrared measurement has principal disadvantages, e.g. in temperature measurement in media, liquids, air currents or surfaces with a low emissivity (polished metals).

There are specially optimised sensor geometries for various applications in liquids, in air currents or on surfaces, which allow correct measurement when using a suitable sensor.
Read and observe information from the thermocouple manufacturer if available.

Using a thermocouple principally requires direct contact with the object measured. Pay attention here to potentially arising hazards and the safety instructions. In this mode, only the temperature of the temperature sensor is measured. Other parameters are excluded here.

Note: Use type K thermocouples only. Measurements may yield incorrect results if other types of thermocouples are connected.

Open the flap (1) and connect the thermocouple at the connection (25).

As soon as a thermocouple is connected, the (n) indicator appears in the display. The measured value of the indicator is continually updated. For the measurement, the measure key (4) must not be pressed in this mode and the lasers are deactivated. To achieve a reliable result, wait for the measured value to stop changing. This can take several minutes depending on the version of thermocouple.

The contact temperature can, however, also be measured in every mode in addition to the surface temperature. Then the measured value is displayed in another place (s). The surface temperature (n) is, however, always used to determine thermal bridges and the risk of mould.

When the thermocouple is removed, the function indicator (s) on the display goes out. Close the flap (1) again after removing the thermocouple.

User mode 

Surface temperature, ambient temperature and relative humidity are measured in user mode. The dew point temperature and the average temperature (average of the surface temperatures during the measuring period) are calculated from these.

You can hide the following values in the display as required: Average temperature, relative humidity, ambient temperature and dew point temperature.

To do so, open the Main Menu (see “Navigating in the Main Menu Select the User Mode  > submenu. You can switch the indicators for<Average Temp Humidity Room Temperature and <Dew Point on and off here.

For surface temperature measurements, you can choose whether the minimum and maximum values (j) of the result scale (k) are adapted automatically or defined  manually. Go to User Mode the menu and then the Scale Range submenu.

• If you want the values (j) to be determined automatically as in surface temperature mode, select . Once the difference between the measurements taken is more than 3 °C, the minimum and maximum temperatures measured during the process will appear on the display (j).
• If you want to define the values manually, select Preset. Set the values you require in the menu under and . The minimum and maximum values you have set manually will appear on the display (j). This enables screenshots of different measurements to be compared using the marking (p), for example.

Surface temperature alarm 

The surface temperature alarm can be used in all modes except contact temperature measurement. You can set a minimum and a maximum temperature.

If the temperature is below the minimum temperature, the temperature alarm indicator (m) flashes blue and (if this feature is switched on) a warning signal sounds.

If the temperature is above the maximum temperature, the temperature alarm indicator (m) flashes red and (if this feature is switched on) a warning signal sounds.

To use the surface temperature alarm, open the Main menu (see “Navigating in the “, page 14).

• Select the Alarm submenu.
• Set <Alarm min/max to on .
• Set the minimum temperature under Alarm min .
• Set the maximum temperature under Alarm max

The minimum and maximum temperatures will remain saved if you set the alarm to <Off.

Note: Use USB to connect the measuring tool to a computer only. The measuring tool may be damaged if connected to other devices.

Data transfer via Bluetooth® 

The measuring tool is equipped with a Bluetooth® module which enables the data taken by your measuring tool to be wirelessly transmitted to a mobile device. Special Bosch applications (apps) are available for this use. These can be downloaded from the respective store of the device.

In addition to wireless data transfer, the Bosch applications make it possible for you to use an extended range of functions and facilitate post editing and forwarding of measured data (e.g. via e-mail). Information about system requirements for a Bluetooth® connection can be found on the Bosch website at www.bosch‑professional.com/thermal. To switch on the Bluetooth® connection on the measuring tool, open the Main menu see “Navigating in the Main menu page 14) and set up Bluetooth on . The indicator (e) appears on the display. Ensure that the Bluetooth® interface is activated on your mobile device. The mobile device and the measuring tool will be paired with each other when the Bosch application is started (providing the Bluetooth® modules are activated). If multiple active measuring tools are found, select the appropriate measuring tool. A connection will be established automatically if only one active measuring tool is found.

Note: When pairing the measuring tool with a mobile device (e.g. smartphone, tablet) for the first time, you may be prompted to enter a PIN code for the measuring tool. If you are, enter “0000”. When transferring data via Bluetooth®, poor reception conditions can cause time delays between the mobile device and the measuring tool.

Setting this parameter can improve the accuracy of the measuring result, especially with low-emissivity (= high-reflection) materials. In some situations (especially in indoor areas), the reflected temperature corresponds to the ambient temperature. If there are objects with greatly deviating temperatures close to highly reflective objects, this value should be adjusted as the measurement may be affected.

Glossary of terms

Infrared thermal radiation
Infrared thermal radiation is electromagnetic radiation emitted by every body. The amount of radiation depends on the temperature and the emissivity of the body.

Emissivity
The emissivity of an object depends on the material and the structure of its surface. This specifies how much infrared thermal radiation the object emits compared with an ideal radiant warmer (black body, emissivity ε = 1) and accordingly has a value between  0 and 1.

Reflected Temperature/Reflectivity of an Object
The reflected temperature is the thermal radiation that is not emitted by the object itself. Depending on the structure and material, background radiation is reflected in the object to be measured, therefore distorting the actual temperature result.

Thermal bridge
A thermal bridge is defined as a position on the external wall of a building, where there is a localised increase in heat loss due to a structural defect.

In order to evaluate the thermal bridges, the minimum requirement of a heat shield outlined according to DIN 4108-2 can be used.

According to DIN 4108-2, the minimum requirement of a heat shield is met if the temperature factor fRsi is larger than 0.7.
The temperature factor fRsi is calculated as follows:

T1: Internal surface temperature
T2: External temperature
T3: Internal ambient temperature

The minimum heat shield acts to avoid mould under standard boundary conditions. This avoids buildings being put in danger.

Under standard conditions (external temperature of –5 °C, internal ambient temperature of 20 °C), the surface temperature should not fall under 12.6 °C. This corresponds to an fRsi limit value of 0.7. For as meaningful a result as possible (small uncertainty), the external temperature should be under 10 °C.

Relative humidity
The relative humidity indicates the degree to which the air is saturated with water vapour. The value is indicated as a percentage of the maximum amount of water vapour the air can absorb. The maximum amount of water vapour depends on the temperature: The higher the temperature is, the more water vapour the air can absorb.
If the relative humidity is too high, there is an increased risk of mould. If the relative humidity is too low, it may have a negative impact on your health.

Dew point temperature
The dew point temperature indicates the point at which the water vapour in the air starts to condense. The dew point temperature depends on the relative humidity and the air temperature.
If the temperature of a surface is below the dew point temperature, water will start to condense on this surface. Condensate on surfaces is one of the main reasons why mould forms.

Maintenance and Service

Maintenance and Cleaning 

Keep the measuring tool clean at all times. A dirty infrared reception lens (23) may impair the measuring accuracy.
Wipe off any dirt using a dry, soft cloth. Do not use any detergents or solvents.
When cleaning the measuring tool, ensure that no liquids enter the tool.

Clean the humidity and temperature sensor (5), camera (22), reception lens (23), light (24) and laser outlet aperture (2) particularly carefully. Make sure that there is no lint on the camera, reception lens or laser beam outlet apertures. Only clean the camera, reception lens and laser beam outlet apertures with cleaning products that are also suitable for camera lenses. Do not attempt to remove dirt from the sensor, camera or reception lens using pointed objects, and do not wipe over the camera and reception lens (risk of scratching).

Do not store the measuring tool for extended periods where the atmospheric humidity is outside the range of 30 % to 50 %. If the measuring tool is stored in conditions that are too damp or too dry, it can result in inaccurate readings. The air humidity sensor is inherently sensitive to solvents, adhesives and softeners. Being influenced by such substances in the long term can lead to deviations in the measured air humidity.

Do not store the measuring tool in a plastic bag, as the evaporation could damage the humidity and temperature sensor (5). Do not affix any stickers near to the sensor on the measuring tool.

Please contact an authorised Bosch after-sales service centre if you want to have your measuring tool recalibrated. Only store and transport the measuring tool in the protective bag provided.

If the measuring tool needs to be repaired, send it off in the protective bag.
