Safety Notes

Read and observe all instructions. The integrated protections in the measuring tool may be compromised if the measuring tool is not used in accordance with the instructions provided.
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.

Have the measuring tool repaired only through qualified specialists using original spare parts. This ensures that the safety of the measuring tool is maintained.
Do not operate the measuring tool in explosive environments, such as in the presence of flammable liquids, gases or dusts. Sparks can be created in the measuring tool which may ignite the dust or fumes.
Before any work on the measuring tool itself (e.g. assembling, maintenance, etc.) as well as when transporting and storing, remove the battery pack or the batteries from the measuring tool.
Do not open the battery pack. Danger of short-circuiting.
Protect the battery pack against heat, e.g.,
against continuous intense sunlight, fire, water, and moisture. Danger of explosion.
When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
Under abusive conditions, liquid may be ejected from the battery pack; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery pack may cause irritations or burns.
In case of damage and improper use of the battery pack, vapours may be emitted. Provide for fresh air and seek medical help in case of complaints. The vapours can irritate the respiratory system.
Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
Use the battery pack only in conjunction with your Bosch measuring tool. This measure alone protects the battery pack against dangerous overload.
The battery pack can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit can occur and the battery pack can burn, smoke, explode or overheat.
The non-rechargeable battery adapter is intended only for use in designated Bosch measuring tools and must not be used with power tools.
Remove the batteries from the measuring tool when not using it for extended periods. When storing for extended periods, the batteries can corrode and self-discharge.
Protect the measuring tool, particularly the area around the camera and infrared lens, against moisture and snow. The reception lens could fog up and distort the measurements. Incorrect settings on the tool and other atmospheric influences may make the measurements inaccurate. Objects could be depicted hotter or colder, which may present a danger if touched.
High temperature differences in a thermal image may cause even high temperatures to be shown in a colour associated with low temperatures. Coming into contact with such an area may cause burns.
Temperature measurements will only be correct if the emissivity setting and the emissivity of the object match. Objects could be depicted hotter or colder in temperature and/or colour, which may present a danger if touched.
Caution! When using the measuring tool with Bluetooth®, interference with other devices and systems, airplanes and medical devices (e.g., cardiac pacemakers, hearing aids) may occur. Also, the possibility of humans and animals in direct vicinity being harmed cannot be completely excluded. Do not use the measuring tool with Bluetooth® in the vicinity of medical devices, petrol stations, chemical plants, areas where there is danger of explosion, and areas subject to blasting. Do not use the measuring tool with Bluetooth ® in airplanes. Avoid operation in direct vicinity of the body over longer periods.
The measuring tool is equipped with a radio interface. Local operating restrictions, e.g. in airplanes or hospitals, are to be observed.

Assembly

Power Supply
The measuring tool can be operated using either commercially available batteries (LR6 AA batteries or similar) or using a Bosch Li-ion rechargeable battery.

Operation with Battery Adapter (Removable) (see figure A)
The batteries are inserted into the battery adapter.

The non-rechargeable 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 cover of the battery adapter 21 into the battery port 18. Place the batteries in the cover as per the illustration on the sealing cap 20. Slide the sealing cap over the cover until you feel it click into place and it is flush with the handle of the measuring tool.

To remove the batteries, press the release buttons 19 of the sealing cap 20 and pull off the sealing cap. In doing so, make sure that the batteries do not fall out. To do this, hold the measuring tool with the battery port 18 facing upwards. Remove the batteries. To remove the inside cover 21 from the battery port 18, reach into the cover recess 22 and pull it out of the measuring tool by applying light pressure to the side wall (see figure B).

Note: Do not use any tools (e.g. a screwdriver) to remove the battery, as this could break the casing. Always replace all batteries at the same time. Only use batteries from one brand and with the identical capacity.

Remove the batteries from the measuring tool when not using it for extended periods. When storing for extended periods, the batteries can corrode and self-discharge.

Operation with Battery Pack (see figure C)
Note: Use of battery packs not suitable for the measuring tool can lead to malfunctions of or cause damage to the measuring tool.

Note: The battery pack is supplied partially charged. To ensure full capacity of the battery pack, completely charge the battery pack in the battery charger before using for the first time.

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

The lithium-ion battery pack can be charged at any time without reducing its service life. Interrupting the charging procedure does not damage the battery pack.

Following the automatic shut off of the measuring tool, do not continue to press the On/Off button. The battery can be damaged.

To insert the charged battery pack 23, slide it into the battery port 18 until you feel it engage and it is flush with the handle of the measuring tool.

To remove the battery pack 23, press the unlocking buttons 19 and pull the battery pack out of the battery port 18. Do not use force to do this.

Battery Status Indicator
The battery status indicator f on the display shows the charging state of the batteries or battery pack 23.

Operation

Protect the measuring tool against moisture and direct sun light.
Do not subject the measuring tool to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for a long time. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. In case of extreme temperatures or variations in temperature, the accuracy of the measuring tool can be impaired.
Make sure that the measuring tool is correctly acclimatised. In the event of severe temperature fluctuations or environmental conditions which vary to a large degree, the measurement accuracy of the measuring tool may be impaired until it is fully acclimatised again.
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 after-sales service agent.

Initial Operation
Switching On and Off
To take a measurement, fold the protective cap 1 upwards. Make sure that the infrared measuring area is not closed off or covered while working.

To switch on the measuring tool, press the On/Off button 9. A start sequence will appear in the display 14. After the start sequence, the measuring tool will immediately begin to measure and will measure continuously until it is switched off.

Note: In the first few minutes, the measuring tool may selfcalibrate several times, as the sensor temperature and ambient temperature have not yet been brought into line. Performing calibration again enables precise measurement. The thermal image freezes briefly during calibration.

To switch off the measuring tool, press the On/Off button again. The measuring tool saves all settings and then switches itself off. Close the protective cap 1 to transport the measuring tool safely.

In the “Settings” menu, you can choose whether and after how much time the measuring tool automatically switches off (see “Switch-off time”, page 22).

If the battery or the measuring tool is not within the operating temperature range stated in the Technical Data, the measuring tool will shut down automatically after a brief warning (see “Troubleshooting – Causes and Corrective Measures”, page 23). Allow the measuring tool to reach to the correct temperature and then switch it back on.

To save energy, only switch the measuring tool on when you are using it.

Preparing for Measurement

Setting the Emissivity Degree for Surface-temperature Measurements

The emissivity degree of an object depends on the material and the structure of its surface. It indicates whether an object (in comparison with other objects with the same temperature) emits much or little infrared heat radiation.

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.

You can select one of the preset emissivity levels or enter an exact numerical value. Adjust the required emissivity using the “Measurement” >“Emissivity” menu (see page 21).

Temperature measurements will only be correct if the emissivity setting and the emissivity of the object match.

Differences in colour may be caused by different temperatures and/or different emissivity levels. If the emissivity levels are very different, the depicted temperature differences may differ considerably from the actual temperature differences.

If there are multiple objects made of different materials or that have different structures in the measurement range, the displayed temperature values are only conclusive for the objects that match the emissivity setting. For all other objects (with different emissivity levels), the displayed colour differences can be used as an indication of temperature relationships.

Notes on the Measuring Conditions
Highly reflective or shiny surfaces (e.g. shiny tiles or polished metals) may distort or impair the results shown. If necessary, mask the surface to be measured with a dark, matt adhesive tape that conducts heat well. Allow the tape to acclimatise briefly on the surface.

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 own body heat may interfere with the measurement when measuring head-on from a perpendicular position. On a level surface, the outline and temperature of your body could therefore be displayed (reflected value), and these values do not correspond to the actual temperature of the measured surface (emitted value or real value of the surface).

Measuring through transparent materials (e.g. glass or transparent plastics) is fundamentally not possible.

The accuracy and reliability of the measuring results increase with better and more stable measuring conditions.

Infrared temperature measurement is impaired by smoke, vapour/ high air humidity or dusty air.

Information for achieving improved measurement accuracy:

Get as close as possible to the measuring object to minimise interfering factors between you and the surface to be measured.
Ventilate indoor areas prior to measurement, especially when the air is contaminated or extremely steamy.

After ventilating, allow the room to acclimatize for a while until the usual temperature has been reached again.

Assigning temperatures on the basis of the scale

A scale is shown on the right-hand side of the display.
The values at the top and bottom end are oriented to the maximum and minimum temperature recorded in the thermal image. Colours are assigned to temperature values with a uniform distribution in the image (linearly).

Different shades can therefore be used to assign temperatures within these two limit values. For example, a temperature that is exactly between the maximum and minimum value can be assigned to the centre colour range of the scale.

To determine the temperature of a specific area, move the measuring tool so that the crosshairs with temperature display l are aimed at the required point or area.

In the automatic setting, the colour spectrum of the scale is always distributed linearly (= uniformly) across the entire measurement range between the maximum and minimum temperatures.

The thermal imaging camera displays all measured temperatures in the measurement range in relation to one another. If heat is displayed as blue in the colour palette in an area, for example in a colour representation, this means that the blue areas are among the colder measured values in the current measurement range. However, these areas may be in a temperature range that could cause injuries in certain circumstances. You should therefore always note the temperatures displayed on the scale or at the crosshairs themselves.

Functions

Adjusting the colour display
Depending on the measurement conditions, different colour palettes can make it easier to analyse the thermal image and show objects or circumstances more clearly in the display. This does not affect the measured temperatures. Only the way in which the temperature values are shown changes. To change the colour palette, remain in measuring mode and press the right-hand 8 or left-hand 12 arrow button.

Superimposition of thermal image and real image
For improved orientation (= local assignment of the thermal image displayed), with matched temperature ranges, a visual real image can additionally be inserted.

Note: The superimposition of the real image and thermal image is accurate at a distance of 0.55 m. If the tool is closer to or further away from the object being measured, this may result in misalignment of the real image and thermal image. The thermal imaging camera offers you the following options:

Complete infrared image
Only the thermal image is displayed.
Image in image
The thermal image displayed is cropped and the surrounding area is shown as a real image. This setting improves the local assignment of the measurement range.
Transparency
The thermal image displayed is placed on top of the real image in such a way that it is slightly transparent. This enables improved detection of objects.

You can adjust the setting by pressing the up 5 or down 10 arrow buttons.

Fixing the scale
The colour distribution in the thermal image is adjusted automatically but can be fixed by pressing the right-hand function button 7. This enables a comparison to be made between thermal images taken under different temperature conditions (e.g. when checking several rooms for thermal bridges).

To switch the scale back to automatic, press the right-hand function button 7 again. The temperatures are now dynamic again and adapt to the measured minimum and maximum values.

Measuring functions
To call up further functions which may be helpful for the display, press the “Func” button 6. Use the right-hand/left-hand buttons to navigate through the displayed options to select a function. Select a function and press the “Func” button 6 again.

The following measuring functions are available:

“Automatic”
Colours are distributed automatically in the thermal image
“Heat detector”
Only the warmer temperatures in the measurement range are displayed as a thermal image in this measuring function. The area outside these warmer temperatures is displayed in greyscale as a real image so that coloured objects are not wrongly associated with temperatures (e.g. red cable in the control cabinet when looking for overheated components). Adjust the scale using the up 5 and down 10 buttons. This expands or reduces the temperature range shown. The tool continues to measure minimum and maximum temperatures and displays these at the ends of the scale. You can, however, control which temperature range is shown in colour as a thermal image.

– “Cold detector”
Only the colder temperatures in the measurement range are displayed as a thermal image in this measuring function. The area outside these colder temperatures is displayed in greyscale as a real image so that coloured objects are not wrongly associated with temperatures (e.g. blue window frame when looking for faulty insulation). Adjust the scale using the up 5 and down 10 buttons. This expands or reduces the temperature range shown.

The tool continues to measure minimum and maximum temperatures and displays these at the ends of the scale. You can, however, control which temperature range is shown in colour as a thermal image.

– “Manual”
If greatly deviating temperatures are measured in the thermal image (e.g. radiator as a hot object when searching for thermal bridges), the available colours are distributed among a large number of temperature values in the range between the maximum and the minimum temperature. This can result in a situation where subtle temperature differences can no longer be shown in detail. To obtain a detailed depiction of the focus temperature, switch to “Manual” mode and set the maximum and the minimum temperature. Doing this enables you to set the temperature range that is relevant to you and in which you would like to detect subtle differences. The Reset setting automatically readjusts the scale to the measured values in the infrared sensor’s field of view.

Main Menu
To access the main menu, press the “Func” button 6 to call up the measuring functions. Now press the right-hand function button 7.

“Emissivity” c:
A selection of saved emissivity levels is available for some of the most common materials. Select the appropriate material in the “Material” menu item. The corresponding emissivity is displayed in the line below.
If you know the exact emissivity of the object to be measured, you can also set it as a numerical value in the “Emissivity” menu item.
“Reflected temperature”:
Setting this parameter improves the accuracy of measuring results, especially with low-emissivity (= high-reflection) materials. The reflected temperature normally corresponds to the ambient temperature.
If there are objects with greatly deviating temperatures close to highly reflective objects which could affect the measurement, this value should be adjusted.

Troubleshooting

– Causes and Corrective Measures

In the event of a fault, the tool will restart and can then continue to be used. If the fault persists, the following overview may help you.

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

Emissivity Degree

The emissivity degree of an object depends on the material and the structure of its surface. It states how much infrared heat radiation the object emits compared to an ideal heat emitter (black body, emissivity degree  = 1).

Thermal Bridge
A thermal bridge is an object that undesirably transmits heat outwards or inwards, therefore differing significantly from the temperature of the rest of a wall or from the desired temperature of a wall.

As the surface temperature at thermal bridges is lower than in the rest of the room, the risk of mould increases significantly at these locations.

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.

Distance from the object
The distance between the object being measured and the measuring tool influences the captured area size per pixel. You can capture increasingly large objects as the distance from the object becomes greater.

TrackMyTools
The built-in Bluetooth® Low Energy Module enables you to personalise and check the status of your measuring tool, as well as transfer settings and data using Bluetooth® wireless technology.

TrackMyTools Bluetooth® module power supply
The measuring tool is fitted with a button cell so that it can still be detected by a mobile device using TrackMyTools without having a battery pack 23 or batteries inserted.

You can find further information directly in the app from Bosch.

Data Transmission
You can switch the TrackMyTools Bluetooth® module on and off in the tool settings. It then emits a continuous signal. The transmission interval of the module is eight seconds. Depending on ambient conditions, up to three transmission intervals may be required before the measuring tool is detected.

Note: Switch TrackMyTools off in areas where the transmission of radio waves is prohibited, for example on aeroplanes. Registering and setting up the app/web-based application

Before you can use TrackMyTools, you need to register online.
To do this, open the website www.bosch-trackmytools.com and register. After registration is complete, you will receive your access information.

Download the app TrackMyTools from the relevant app store (Apple App Store, Google Play Store) or access the web application at https://web.bosch-trackmytools.com, where you can log in using your access details.

You can now create and manage your inventory using the app/web-based application.

Note: First, complete the tutorial for the app/web-based application.
This will provide you with a better overview of the procedure for creating the inventory and using the software.
