Safety Instructions
All instructions must be read and observed.
The safeguards integrated into the measur-
ing tool may be compromised if the measur-
ing tool is not used in accordance with these
instructions. STORE THESE INSTRUCTIONS IN A SAFE
PLACE.
uHave 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 main-
tained.
uDo not use the measuring tool in explosive atmo-
spheres which contain flammable liquids, gases or
dust. Sparks may be produced inside the measuring tool,
which can ignite dust or fumes.
uDo not open the battery. There is a risk of short-circuit-
ing.
uIn case of damage and improper use of the battery, va-
pours may be emitted. The battery can set alight or ex-
plode. Ensure the area is well ventilated and seek medical
attention should you experience any adverse effects. The
vapours may irritate the respiratory system.
uIf used incorrectly or if the battery is damaged, flam-
mable liquid may be ejected from the battery. Contact
with this liquid should be avoided. If contact accident-
ally 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 ir-
ritation or burns.
uThe 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.
uWhen the battery is not in use, keep it away from pa-
per 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.
uOnly use the battery with products from the manufac-
turer. This is the only way in which you can protect the
battery against dangerous overload.
uOnly charge the batteries using chargers recommen-
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.
uRemove the rechargeable battery/non-rechargeable
batteries from the measuring tool before carrying out
work on the measuring tool (e.g. assembly, mainten-
ance, etc.). The battery/batteries should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
uThe battery adapter is intended only for use in desig-
nated Bosch measuring tools and must not be used
with power tools.
uTake the batteries out of the measuring tool when you
are not using it for a prolonged period of time. The bat-
teries can corrode and self-discharge during prolonged
storage in the measuring tool.
uProtect 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 influ-
ences 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.
uHigh 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.
uTemperature measurements will only be correct if the
emissivity setting matches the emissivity of the ob-
ject. Otherwise, object temperatures could be shown to
be hotter or colder than they are, which may present a
danger if touched.
uDo not point the measuring tool directly at the sun or
at high-performance CO₂ lasers. This may damage the
detector.
uThe measuring tool is equipped with a wireless inter-
face. 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 oper-
ating manual.
Intended Use
This thermal imaging camera is designed for the contactless
measurement of surface temperatures.
The displayed thermal image shows the temperature distri-
bution 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 differ-
ences and discrepancies in order to make components and/
or any weaknesses visible, including:
– Thermal insulation and other types of insulation (e.g. loc-
ating thermal bridges)
– Active heating and hot water pipes (e.g. underfloor heat-
ing) in floors and walls
1 609 92A 7CX | (27.01.2022) Bosch Power Tools
English | 7
– Overheated electrical components (e.g. fuses or termin-
als)
– Faulty or damaged machine parts (e.g. overheating due to
faulty ball bearings)
The measuring tool is not suitable for measuring the temper-
ature of gases.
The measuring tool may not be used to measure the body
temperature of humans or animals or for other medical pur-
poses.
The measuring tool is suitable for indoor and outdoor use.

Assembly
Power supply
The measuring tool can be operated either with conventional
non-rechargeable batteries or with a Bosch lithium-ion bat-
tery.
Operation with battery adapter (removable)
(seefiguresAandB)
The batteries are inserted into the battery adapter.
uThe battery adapter is intended only for use in desig-
nated Bosch measuring tools and must not be used
with power tools.
To insert the batteries, slide the receptacle(21) of the bat-
tery 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. Re-
move the batteries. To remove the receptacle(21) from in-
side 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.
uTake the batteries out of the measuring tool when you
are not using it for a prolonged period of time. The bat-
teries can corrode and self-discharge during prolonged
storage in the measuring tool.
Operation with rechargeable battery (seefigureC)
Note: The use of batteries unsuitable for your measuring tool
can lead to malfunctions or damage to the measuring tool.
uUse 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 bat-
tery 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
uProtect the measuring tool from moisture and direct
sunlight.
uDo not expose the measuring tool to any extreme tem-
peratures 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 measur-
ing tool to adjust to the ambient temperature before put-
ting it into operation. The precision of the measuring tool
may be compromised if exposed to extreme temperat-
ures or variations in temperature.
uMake sure that the measuring tool is correctly accli-
matised. In case of large variations in temperature, accli-
matisation can take up to 60minutes. 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.
uAvoid hard knocks to the measuring tool or dropping
it. After severe external influences and in the event of ab-
normalities 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) up-
wards. 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 un-
til it is switched off.
Note: In the first few minutes, the measuring tool may self-
calibrate several times, as the sensor temperature and ambi-
ent temperature have not yet been brought into line. Per-
forming sensor calibration again enables precise measure-
ment.
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 trans-
port 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", page11).
If the battery pack or the measuring tool is not within the op-
erating temperature range specified in the technical data,
the measuring tool will switch off automatically after a brief
warning (see "Errors – Causes and Corrective Measures",
page13). 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 accord-
ingly has a value between 0 and 1.
To determine the surface temperature, the tool performs a
contactless measurement of the natural infrared thermal ra-
diation 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 measure-
ment 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 ex-
act numerical value. Set the required emissivity via the
<Measurement>→ <Emissivity> menu (see "Main Menu",
page11).
uTemperature 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 reflec-
ted temperature on the measuring result. Always adjust the
reflected temperature when changing the emissivity. Set the
reflected temperature via the <Measurement>→
<Reflected temp.> menu (see "Main Menu", page11).
Temperature differences allegedly shown by the measuring
tool may be caused by different temperatures and/or differ-
ent emissivity levels. If the emissivity levels are very differ-
ent, the depicted temperature differences may differ consid-
erably from the actual temperature differences.
If there are multiple objects made of different materials or
that have different structures in the measuring range, the
displayed temperature values are only accurate for the ob-
jects that match the emissivity setting. For all other objects
(with different emissivity levels), the displayed colour differ-
ences can be used as an indication of temperature relation-
ships.
Information about the Measuring Conditions
Highly reflective or shiny surfaces (e.g. shiny tiles or pol-
ished metals) may significantly distort or impair the results
shown. If necessary, mask the measuring surface with a
dark, matt adhesive tape that conducts heat well. Allow the
tape to briefly reach the correct temperature on the surface.
Make sure that a favourable measuring angle is used on re-
flective surfaces in order to ensure that the thermal radiation
reflected by other objects does not distort the result. For ex-
ample, the reflection of your own emitted body heat may in-
terfere 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 (re-
flected value), and these values do not correspond to the ac-
tual temperature of the measured surface (emitted value or
real value of the surface).
Measuring through transparent materials (e.g. glass or trans-
parent plastics) is fundamentally not possible.
Consequently, the more suitable and stable the measuring
conditions are, the more accurate and reliable the measure-
ment readings are. Not only do significant fluctuations in the
temperature of the environmental conditions have an im-
pact, the accuracy can also be impaired by significant fluctu-
ations in the temperatures of the object being measured.
Infrared temperature measurement is impaired by smoke,
steam/high humidity or dusty air.
Information for achieving improved measurement accuracy:
– Move as close as possible to the object to be measured 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. Once
ventilated, allow the room to reacclimatise a while until it
returns to the usual temperature.
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 evalu-
ated. Colours are assigned to temperature values
with a uniform distribution in the image (lin-
early).
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 measur-
ing range between the maximum and minimum temperat-
ures.
The measuring tool displays all measured temperatures in
the measuring range in relation to one another. If heat is dis-
played 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 dis-
played 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
1 609 92A 7CX | (27.01.2022) Bosch Power Tools
English | 11
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 dis-
played.
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 im-
age corresponds exactly at a distance of 0.55m. 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 GTCTransferSoftware.
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 sur-
rounding area is shown as a real image. This setting im-
proves 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 auto-
matically but can be fixed by pressing the right-hand func-
tion 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 dy-
namic again and adapt to the measured minimum and max-
imum values.
Measuring Functions
To call up further functions that may be helpful for the dis-
play, press theFunc(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 theFunc(6) button again.
The following measuring functions are available:
–<Automatic>
Colours are distributed automatically in the thermal im-
age.
–<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 grey scale. The depiction in grey scale pre-
vents 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 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 grey scale to prevent coloured objects from
being wrongly associated with temperatures (e.g. a blue
window frame when searching for faulty insulation). Ad-
just the scale using the up arrow button(5) and down ar-
row button(10). This expands or reduces the temperat-
ure range, thereby expanding or reducing the thermal im-
age. The measuring tool continues to measure 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<Manual> mode, you can 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
scale> setting automatically readjusts the scale to the
measured values in the infrared sensor's field of view.

exact emissivity of the object you want to measure,
you can also set it as a numerical value in the
<Emissivity> menu item.
▪<Reflected temp.>(b)
Setting this parameter can improve the accuracy of the
measuring result, especially with low-emissivity
(=high-reflection) materials. In some situations (espe-
cially in indoor areas) the reflected temperature cor-
responds to the ambient temperature. If there are ob-
jects with greatly deviating temperatures close to
highly reflective objects, this value should be adjusted
as the measurement may be affected.

Post-Editing the Thermal Images
You can post-edit the saved thermal images on your com-
puter if it uses a Windows operating system. To do so, down-
load the GTC Transfer software from the product page for
the measuring tool at www.bosch-professional.com.
Data transmission via WLAN
The measuring tool is equipped with a Wi‑Fi® interface which
enables the saved images taken by your measuring tool to be
wirelessly transmitted to a mobile device.
Special Bosch applications (apps) are available for this use.
They can be downloaded in the store corresponding to your
device:
In addition to the wireless data transfer of your images, the
Bosch applications make it possible for you to use an exten-
ded range of functions and make it easier to post-edit and
forward measured data (e.g. via e-mail). Information about
system requirements for a Wi‑Fi® connection can be found
on the Bosch website at www.bosch-professional.com.
To activate or deactivate the Wi‑Fi® connection on the meas-
uring tool, call up the main menu, use the buttons to
select<WiFi> and activate or deactivate it. The indicator(d)
appears in the display when the Wi‑Fi® is activated. Ensure
that the Wi‑Fi® interface is activated on your mobile device.
The connection between the mobile device and the measur-
ing tool can be established after the Bosch application has
been started (if the Wi‑Fi® modules are activated). To do
this, follow the instructions in the application (app).

Glossary of terms
To find out more, visit: www.bosch-professional.com.
Infrared thermal radiation
Infrared thermal radiation is electromagnetic radiation emit-
ted by every body above 0Kelvin (−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 accord-
ingly 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

u请勿在极端温度或温度波动较大的情况下使用测
量仪。比如请勿将测量仪长时间放在汽车内。温
度波动较大的情况下，使用测量仪之前先使其温
度稳定下来。如果仪器曝露在极端的气候下或温
差相当大的环境中，会影响仪器的测量准确度。
u注意测量仪正确的气候适应性。温度波动较大
时，气候适应时长最多为60分钟。比如，如果将
测量仪存放在温度较低的车中，然后在温暖的建
筑中进行测量，则可能是这种情况。
u避免测量仪剧烈碰撞或掉落。在发生强烈的外界
作用后以及功能异常时，应将测量仪交由授权的
Bosch售后服务点进行检查。
接通/关闭
测量时打开保护盖(1)。在工作中请注意不要封闭或
遮挡红外线传感器。
如要接通测量仪，请按压电源开关(9)。在显示屏
(14)中显示启动序列。启动顺序结束后，测量仪立
刻开始测量并自动连续运行直至关闭。
提示：在最初几分钟内，测量仪可能会自动频繁调
校，因为此时传感器温度和环境温度尚未完成匹
配。重新调校传感器后可以精确测量。
在这段时间内可以用~标记温度显示。热成像在传感
器调校期间会短时冻结。当环境温度剧烈波动时，
该影响加剧。因此，应尽可能地在开始测量前的几
分钟接通测量仪，使其热稳定。
如要关闭测量仪，请重新按压电源键(9)。测量仪保
存所有设置，然后自动关闭。请合上保护盖(1)，以
确保安全运输测量仪。
您可以在主菜单中选择是否以及多久之后自动关闭
测量仪(参见 “主菜单”, 页19)。
如果充电电池或测量仪超出技术参数规定的工作温
度，则测量仪在短促警告(参见 “故障 – 原因和解
决措施”, 页21)后自动关闭。使测量仪冷却，然
后再次接通。
测量准备
调整表面温度测量的辐射率
物体辐射率取决于其表面的材质和结构。它表示，
与理想的热辐射器（黑色物体，辐射率ε=1）相
比，该物体发出的红外热辐射量，数值在0至1之
间。
要确定表面温度，请以非接触方式测量所显示物体
发射出的天然红外热辐射。为了确保正确测量，必
须在每次测量前检查测量仪上设置的辐射率，必要
时与测量物体进行匹配。
测量仪中预设的辐射率为基准值。
您可以选择一个预设好的辐射率，或者输入一个具
体的数值。通过菜单<测量>→ <辐射率>设置所需
的辐射率 (参见 “主菜单”, 页19)。
u只有当设置的辐射率和物体辐射率一致时，才能
正确测量温度。
辐射率越小，反射温度对测量结果的影响越大。因
此，在更改辐射率时务必调整反射温度。通过菜单<
测量>→ <反射温度>调整反射温度 (参见 “主菜
单”, 页19)。
测量仪显示的假定色差可能是由不同的温度和/或不
同的辐射率导致的。如果辐射率差别较大，显示的
温差会明显偏离实际温差。
如果测量范围内有不同材料或不同结构的多个测量
物体，那么显示的温度值仅对与设定的辐射率相匹
配的物体精确。对于所有其它（具有不同辐射率
的）物体，显示的色差可以用作温度关系提示。
测量条件提示
高反射或光泽表面（例如光泽的瓷砖或光亮的金
属）可能严重影响显示的测量结果或导致其失真。
需要时用导热良好的深色亚光胶带贴住测量面。让
胶带短暂地在表面上调温。
对于反射表面请确保良好的测量角度，这样其它物
体的反射热辐射不会使测量结果失真。例如，从前
面垂直测量时，您自身的体热辐射会影响测量。在
测量平整表面时，这样会显示您的身体轮廓和体温
（反射值），而非被测表面的本来温度（表面的测
得值或实际值）。
原则上，无法穿过透明材料（例如玻璃或透明塑
料）进行测量。
测量条件越好越稳定，测量结果就越确切可靠。这
不仅与环境条件的温度波动相关，所测物体剧烈的
温度波动也会影响精度。
烟、蒸汽/高湿度或含有粉尘的空气将影响红外温度
测量。
提高测量精度的提示：
– 请尽可能靠近测量物体，将您与测量表面之间的
干扰因素降至最低。
– 在测量前为室内通风，尤其是当空气较脏或有大
量水汽时。通风后使房间调温一会儿，直至重新
达到常温。

根据刻度匹配温度
显示屏的右侧显示有刻度(g)。上端和下端
的数值对应于热成像中测得的最高温度(f)
或最低温度(h)。为该刻度尺计算整个像素
的99.8%。热成像中颜色与温度值划分是
均匀（线性）分配的。
因而可以利用不同的色调在这两个边界值
范围内分配温度。正好位于最高值和最低
值中心的温度例如已分配给刻度中间的颜
色区域。
在测定具体范围的温度时，请移动测量仪，使带有
温度显示的十字线(k)对准需要测量的点或范围。在
自动设置中，刻度的色谱总是线性（=均匀）地分配
在最高和最低温度之间的整个测量范围上。
测量仪显示测量范围内所有测得的温度，相互之间
成比例显示。如果在某个范围内，例如在某个彩色
显示图内，调色板中的热量显示为淡蓝色，那么说
明淡蓝色范围属于当前测量范围内温度相对较低的
测量值。但是这些范围却可能处于一个可导致受伤
的温度区域内。因此，请始终在刻度表上或直接在
十字线上观察显示的温度。
功能
彩色显示的匹配
根据测量情况，不同的调色板可以方便热成像的分
析，并清晰地在显示屏上显示物体或实际情况。这
不会影响测得的温度。它只改变温度值的显示。
切换调色板时，请停留在测量模式，按压向右箭头
键(8)或向左箭头键(12)。
热成像和真实图像重叠
为了更好地定位（=所显示热成像的空间位置匹
配），可以在调整好温度范围后另外叠加一张视觉
真实图像。
提示：真实图像和热成像的叠加在0.55米的距离上
最准确。如果与测量物体的距离存在偏差，则受原
理限制，会导致真实图像和热成像偏移。该偏移可
以通过GTC Transfer软件进行补偿。
本测量仪具有以下功能：
–100%红外图像
仅显示热成像。
–画中画
显示的热成像经过剪裁，四周区域显示真实图
像。该设置改进了测量范围的局部分配。
–透明度
显示的热成像以透明的形式叠在真实图像上方。
这样能够更好地识别物体。
通过按压向上箭头键(5)或向下箭头键(10)，您可以
选择该设置。
固定刻度
热成像中的颜色分配是自动进行调整的，但是可以
通过按压右侧功能键(7)进行冻结。这样就可以对不
同温度条件下测得的热成像进行比较（例如在检测
多个空间的热桥时）或者在热成像中隐藏极冷或极
热的物体，否则可能会扭曲（比如查找热桥时将散
热器测为高温物体）。
如需重新将刻度切换为自动，请再次按下右侧功能
键(7)。温度现在重新动态变化，根据测得的最高值
和最低值进行调整。
测量功能
如需调用其它可在显示中提供帮助的功能，请按压
按键Func(6)。在显示的选项中用向左箭头键(12)
或向右箭头键(8)导航，以选择某个功能。选择一个
功能，然后再次按下按键Func(6)。
有以下测量功能可用：
–<自动>
在热成像中自动进行颜色分配。
–<热态搜索器>
在该测量功能下只会把测量范围内较热的温度显
示为热成像。这些较热温度以外的范围将显示为
灰阶真实图像。通过灰阶进行显示可以避免将彩
色物体错误地与温度联系起来（例如在查找过热
的零部件时与电气柜内的红色电缆混淆）。用向
上箭头键(5)和向下箭头键(10)调整刻度。这样可
以作为热成像放大或缩小显示的温度范围。本测
量仪仍然同时测量最低和最高温度，并显示在刻
度(g)的两端。
–<冷态搜索器>
在该测量功能下只会把测量范围内较冷的温度显
示为热成像。这些较冷温度以外的范围将显示为
灰阶真实图像，以免将彩色物体错误地与温度联
系起来（例如在查找有问题的绝缘层时与蓝色窗
框混淆）。用向上箭头键(5)和向下箭头键(10)调
整刻度。这样可以作为热成像放大或缩小显示的
温度范围。本测量仪仍然同时测量最低和最高温
度，并显示在刻度(g)的两端。
–<手动>
如果热成像中测得的温差较大（例如在检查热桥
时将散热器测为高温物体），那么可用的颜色将
分布在最高和最低温度之间的众多温度值上。这
可能会导致无法再详细地显示细微的温差。为了
能够详尽地显示待检查的温度范围，请按以下方
式操作：在切换到<手动>模式后，您可以设置最
高或最低温度。这样就可以设定与您相关的温度
范围，从而能够识别细微的区别。在<复位标尺>
设置中，刻度又可以根据红外传感器视野范围内
的测量值自动进行调整。
主菜单
如需进入主菜单，请按下按键Func(6)，以调出测
量功能。现在按下右侧功能键(7)。

应辐射率显示在下面一行中。如果您已知测量
物体的确切辐射率，也可在菜单项<辐射率>中
以数值形式设置该辐射率。
▪<反射温度> (b)
这个参数的设置可以改善测量结果，特别是对
于辐射率较低（=高反射）的材料。在某些情况
下（尤其是在室内），反射温度就是环境温
度。如果反射强烈的物体附近有温差较大的物
体会影响测量，那么应调整该数值。
–<显示>
▪<中心点> (k)
该点显示在热成像的中间，为您显示此位置上
测得的温度值。
▪<热点> (j)：<打开>/<关闭>
在热成像中用红色十字线标记最热点（=测量像
素）。这样可以更轻松地查找临界位置（比如
开关柜中松动的触点端子）。
▪<冷点> (l)：<打开>/<关闭>
在热成像中用蓝色十字线标记最冷点（=测量像
素）。这样可以更轻松地查找临界位置（比如
窗中的不密封位置）。
▪<色标> (g)：<打开>/<关闭>
–<WiFi> (d): <打开>/<关闭>
(参见 “数据传输”, 页20)
–<设备>
▪<语言>
在该菜单项下，您可以选择显示中使用的语
言。
▪<时间/日期> (a)
