Safety instructions
- 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 warning label (marked in the illustration of the measuring tool on the graphics page).
- If the text on the warning label is not in your native language, cover it with the label supplied, which is in your language, before initial commissioning.
- 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 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 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 accidentally dazzle someone.
- 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.
- The measuring tool may not be 100% accurate for technological reasons. Environmental factors (e.g. dust or steam in the area being measured), temperature fluctuations (e.g. from fan heater) as well as the nature and condition of the surfaces being measured (e.g. highly reflective or transparent materials) can distort measurement readings.
- Protect the measuring tool, particularly the area around the infrared lens and laser, from 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. Otherwise, object temperatures could be shown to be hotter or colder than they are, which may present a danger if touched.
- Temperature measurements will only be correct if the emissivity setting matches the emissivity of the object. Otherwise, object temperatures could be shown to be hotter or colder than they are, which may present a danger if touched.
- Take the batteries out of the measuring tool when it is being stored or transported. Persons are at risk of being blinded if the on/off switch is unintentionally pressed.

Assembly
Inserting/changing the batteries
It is recommended that you use alkaline manganese batteries to operate the measuring tool.
To open the battery compartment cover (4), press the locking mechanism (5) and lift open the battery compartment cover. Insert the batteries. When inserting the batteries, ensure the polarity is correct according to the representation on the inside of the battery compartment cover.
The battery indicator (a) shows the batteries’ state of charge:
| Indicator | Capacity |
| 67 % to 100 % | |
| 34 % to 66 % | |
| 15 minutes…<33 % | |
| Maximum 15 minutes |
If the battery indicator (a) flashes with the empty battery symbol, the batteries must be replaced.
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.
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 30 minutes. This may be the case, for example, if you first perform a measurement in the cool cellar and then go up to the warm attic.
- 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.
- Do not close or cover the reception lens (2) or the laser outlet aperture (1).
Switching on/off
The following options are available for switching on the measuring tool:
- Switch on the measuring tool using the on/off button (9). After a brief start-up sequence, the measuring tool is ready to use with the unit of measurement that was saved when the tool was last switched off. No measurement is initiated at this stage and the laser is still switched off.
- Switch on the measuring tool using the measuring button (3). After briefly pressing the measuring button (3), the measuring tool will be ready to take measurements following a brief start-up sequence. If you press and hold the measuring button (3) for more than three seconds, the laser will be switched on after the start-up sequence and the measuring tool will immediately begin measuring with the last saved unit of measurement.
- 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).
To switch off the measuring tool, press the on/off button (9).
If no button on the measuring tool is pressed for approx. 1 minutes, the measuring tool will automatically switch off to preserve battery life.
Measurement preparations
Setting the unit of measurement
The default unit of measurement is degrees Celsius (°C). You can switch between the degrees Celsius and degrees Fahrenheit units of measurement by pressing and holding the button Mode (8) for more than three seconds.
If the measuring tool is switched on and the unit of measurement is changed, the last set of measured values will be erased. The unit of measurement is saved and displayed when you switch on the measuring tool again.
Adjusting the emissivity
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. For optimum measuring results, the emissivity setting (see “Emissivity”, page 26) on the measuring tool must be checked before every measurement and adapted to the object being measured if necessary.
When the measuring tool is switched on, the high emissivity setting is activated by default. If the emissivity is changed, the last set of measured values will be erased.
You can select from three different emissivity settings on the measuring tool. The following table shows commonly used materials of a similar emissivity for each emissivity setting; note that these are examples and not an exhaustive list. Because the emissivity of a material is dependent on a variety of factors and is therefore variable, the details in the following overview serve only as guide values.
The following emissivity gradings are used:
- High emissivity grading: Approx. 0.95
- Medium emissivity grading: Approx. 0.85
- Low emissivity grading: Approx. 0.75
To change the emissivity setting, press the button Mode (8) repeatedly until the emissivity indicator (d) shows the required emissivity for the next measurement.
- Temperature measurements will only be correct if the emissivity setting matches the emissivity of the object. Otherwise, object temperatures could be shown to be hotter or colder than they are, which may present a danger if touched.
Measuring surface
The infrared radiation of the measuring surface is determined during the contactless measurement of the surface temperature.
The laser point marks the approximate centre of the measuring surface. For an optimum measurement reading, position the measuring tool so that the laser beam meets the measuring surface perpendicularly to this point.
- 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 being measured increases the size of the measuring surface. At a distance of 1 m, the measuring surface is approx. 8.3 cm in size if the laser beam is perpendicular to a flat measuring surface.
At a surface temperature of -10 °C to +500 °C, the optimum measuring distance is between 0.75 m and 1.25 m. Below -10 °C, the optimum measuring distance is between 10 cm and 30 cm.
The displayed reading is the average value of all temperatures measured within the measuring surface.
- Stand back from very hot objects. There is a risk of burns.
- Do not hold the measuring tool directly against hot surfaces. The heat can damage the measuring tool.
Information about the measuring conditions
Highly reflective or glossy surfaces (e.g. glossy tiles, stainless steel fronts or cooking pots) can affect the surface temperature measurement. 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.
Measuring through transparent materials (e.g. glass or transparent plastics) is fundamentally not possible.
Consequently, the more suitable and stable the measuring conditions are, the more accurate and reliable the measurement readings are.
Infrared temperature measurement is impaired by smoke, steam 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.
Measuring functions
Individual measurements
Briefly pressing the measuring button (3) once switches the laser on and actuates a single measurement.
The measuring process can take up to half a second and is indicated by the SCAN (i) indicator lighting up. Once the measurement has been completed, the laser switches off automatically, the indicator SCAN disappears and both the most recent measurement reading and the reading before it are shown on the display.
Continuous measurement
For continuous measurements, press and hold the measuring button (3). The laser remains switched on and the indicator SCAN appears in the display. Using slow movements, aim the laser at each of the surfaces to be measured, one by one.
The indicator on the display is continually updated. As soon as you let go of the measuring button (3), the measurement is stopped, the indicator SCAN disappears and the laser is switched off.
The most recent measurement reading and the reading before it are shown on the display.
Errors - causes and corrective measures
Measuring tool not acclimatised
The measuring tool has been subjected to extreme fluctuations in temperature and did not have sufficient time to adjust.
Ambient temperature outside the operating temperature range
The ambient temperature is too high or too low for the measuring tool to operate.
Surface temperature outside the measuring range
The indicator flashes if the surface temperature of the object being measured in the measuring area is too high (above 500 °C, see indicator (h)) or too low (below -30 °C, see indicator (g)). The temperature of this object cannot be measured. Aim the laser at another object and start a new measurement.
Internal error
If the measuring tool has an internal fault, Err is shown on the display and the (j) symbol flashes. To reset the software, remove the batteries, wait a few seconds and then reinsert the batteries.
If the error persists, have the measuring tool checked by a Bosch customer service agent. Do not open the measuring tool yourself.
Glossary of terms
Emissivity
The emissivity of an object depends on the material and the structure of its surface. It indicates whether a particular object emits a high or low level of infrared thermal radiation (in comparison to other objects of the same temperature).
Maintenance and Service
Maintenance and Cleaning
- Check the measuring tool before each use. If the measuring tool is visibly damaged or parts have become loose inside the measuring tool, safe function can no longer be ensured.
Only store and transport the measuring tool in a suitable container, such as the original packaging. Do not affix any stickers near to the sensor on the measuring tool.
Always keep the measuring tool clean and dry to ensure optimum, safe operation.
Never immerse the measuring tool in water or other liquids.
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 reception lens (2) and laser outlet aperture (1) very carefully:
Ensure that there is no lint on the reception lens or the laser outlet aperture. Do not attempt to remove dirt from the reception lens using pointed objects, and do not wipe over the reception lens (risk of scratching). If necessary, you can carefully blow away dirt using oil-free compressed air.
If repairs are required, send in the measuring tool in its original packaging.
