Safety Instructions
**** All instructions must be read and observed. The safeguards integrated into the measuring tool may be compromised if the measuring tool is not used in accordance with these instructions. STORE THESE INSTRUCTIONS IN A SAFE PLACE.
-
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 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 vapors 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. u 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- ded 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-ance, etc.). The battery/batteries should also be removed for transport and storage. There is a risk of injury from unintentionally pressing the on/off switch.
-
The battery adapter is intended only for use in designated Bosch measuring tools and must not be used with power tools.
-
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.
-
Protect the measuring tool, particularly the area around the camera and infrared lens, 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.
-
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 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.
-
Do not point the measuring tool directly at the sun or at high-performance CO₂ lasers. This may damage the detector.
-
The measuring tool is equipped with a wireless interface. Local operating restrictions, e.g. in aeroplanes or hospitals, must be observed.
Product Description and Specifications
Please observe the illustrations at the beginning of this operating manual.
Intended Use
This thermal imaging camera is designed for the contactless measurement of
surface temperatures. The displayed thermal image shows the temperature
distribution in the thermal imaging camera’s field of view and therefore
enables temperature deviations to be depicted in different colours.
When used correctly, this makes it possible to examine areas and objects in a
contactless manner for temperature differences and discrepancies in order to
make components and/ or any weaknesses visible, including:
– Thermal insulation and other types of insulation (e.g. locating thermal
bridges)
– Active heating and hot water pipes (e.g. underfloor heating) in floors and
walls
– Overheated electrical components (e.g. fuses or terminals)
– Faulty or damaged machine parts (e.g. overheating due to faulty ball
bearings) The measuring tool is not suitable for measuring the temperature of
gases. 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 suitable for indoor and outdoor use.

measuring tool.
Assembly
Power supply
The measuring tool can be operated either with conventional non-
rechargeable batteries or with a Bosch lithium-ion battery.
Operation with battery adapter (removable) (see figures A and 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 (21) of the battery adapter into the battery bay (18). Place the batteries in the receptacle as shown in the picture on the cap (20). Push the cap over the receptacle until you feel it click into place.
To remove the batteries, press the release buttons (19) on the cap (20) and pull the cap off. Hold the measuring tool with the battery bay (18) facing upwards to ensure that the batteries do not fall out when you do this. Remove the batteries. To remove the receptacle (21) 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.
Note: Do not use any tools (e.g. a screwdriver) to remove the battery, as this could break the cover. 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 (see figure C)
Note: The use of batteries unsuitable for your measuring tool can lead to
malfunctions or damage to the measuring tool.
- Use only the chargers listed in the technical data. Only these chargers are matched to the lithium-ion battery of your measuring tool. 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 (23), slide it into the battery bay (18) until you feel it click into place and it is flush with the handle of the measuring tool. To remove the battery pack (23), press the release buttons (19) and pull the battery pack out of the battery bay (18). Do not use force to do this.
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 after-sales service agent.
Switching On and Off
To take a measurement, fold the protective cap (1) upwards. Make sure that the
infrared sensor 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 on the display (14). The measuring tool begins to take
measurements as soon as the start sequence has finished and does so
continuously until it is switched off.
Note: In the first few minutes, the measuring tool may self calibrate
several times, as the sensor temperature and ambient temperature have not yet
been brought into line. Performing sensor calibration again enables precise
measurement.
During this time, the temperature indicator may show ~. The thermal image will
freeze briefly during sensor calibration. If the ambient temperature
fluctuates significantly, this effect is increased. If possible, you should
therefore turn on the measuring tool a few minutes before starting to measure,
so that the tool can stabilise thermally.
To switch off the measuring tool, press the on/off button (9) 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 main menu, you can choose whether and after how long the measuring tool
automatically switches off (see “Main Menu”, page 11). If the battery pack or
the measuring tool is not within the operating temperature range specified in
the technical data, the measuring tool will switch off automatically after a
brief warning (see “Errors – Causes and Corrective Measures”, page 13). Allow
the measuring tool to reach the correct temperature and then switch it back
on.
**Measurement Preparations
**
Setting the emissivity for surface temperature measurements
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.
To determine the surface temperature, the tool performs 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 emissivities or
enter an exact numerical value. Set the required emissivity via the
- Temperature measurements will only be correct if the emissivity setting and the emissivity of the object match.
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 **
Assigning Temperatures on the Basis of the Scale
A scale (g) is shown on the right-hand side of the display. The values at
the top and bottom end are oriented to the maximum (f) and minimum (h)
temperature recorded in the thermal image. For the scale, 99.8 % of the total
pixels are evaluated. 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 is 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 (k) 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 measuring range
between the maximum and minimum temperatures.
The measuring tool displays all measured temperatures in the measuring 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 measuring range.
However, these areas may still be in a temperature range which 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 may make it
easier to analyse the thermal image and display objects or circumstances more
clearly in the display. This does not affect the measured temperatures. The
only change is the way in which the temperature values are displayed.
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 real visual image can additionally be
inserted.
Note: The superimposition of the real image and thermal image corresponds
exactly at a distance of 0.55 m. If the tool is closer to or further away from
the object being measured, this fundamentally results in misalignment of the
real image and thermal image. This misalignment can be compensated for with
the GTC Transfer Software.
The measuring tool camera offers you the following options:
– Complete infrared image
Only the thermal image is displayed.
– Picture-in-picture
The thermal image displayed is cropped and the surrounding area is shown as
a real image. This setting improves the local assignment of the measuring
range.
– Transparency
The thermal image displayed is placed on top of the real image in such a
way that it is transparent. This enables improved detection of objects. You
can select 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). It also
allows an extremely cold or hot object to be hidden in the thermal image. This
object would otherwise distort the image (e.g. a radiator as a hot object when
searching 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 that may be helpful for the display, press the
Func (6) button. Use the left-hand arrow button (12) or the right-hand arrow
button (8) to navigate through the displayed options to select a function.
Select a function and press the Func (6) button again.
The following measuring functions are available:
– < Automatic> Colours are distributed automatically in the thermal image.
– < Heat detector> Only the warmer temperatures in the measuring range are
displayed as a thermal image in this measuring function. The area outside
these warmer temperatures is shown as a real image in greyscale. The depiction
in grey scale prevents coloured objects from being wrongly associated with
temperatures (e.g. a red cable in the control cabinet when searching for
overheated components). Adjust the scale using the up arrow button (5) and
down arrow button (10). This expands or reduces the temperature range, thereby
expanding or reducing the thermal image. The measuring tool continues to
measure the minimum and maximum temperatures and displays these at the ends of
the scale (g).
– < Cold detector> Only the colder temperatures in the measuring range are
displayed as a thermal image in this measuring function. The area outside
these colder temperatures is shown as a real image in greyscale to prevent
coloured objects from being wrongly associated with temperatures (e.g. a blue
window frame when searching for faulty insulation). Adjust the scale using the
up arrow button (5) and down arrow button (10). This expands or reduces the
temperature range, thereby expanding or reducing the thermal image. The
measuring tool continues to measure the minimum and maximum temperatures and
displays these at the ends of the scale (g).
– < Manual> If greatly deviating temperatures are measured in the thermal
image (e.g. a 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 temperature range to be
examined, take the following steps: After switching to

Infrared thermal radiation
Infrared thermal radiation is electromagnetic radiation emitted by every body
above 0 Kelvin (−273 °C). 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.
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.
Thermal bridges can lead to an increased risk of mould.
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.
Distance (m)| Size of infrared pixels (mm)| Infrared range width
× height (m)
---|---|---
0.5| 3| –0.5 × 0.4
1| 6| –1 × 0.75
2| 12| –2.05 × 1.5
5| 30| –5.1 × 3.8
Maintenance and Service
Maintenance and Cleaning
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
