3.3 Power supply
The power is supplied to the instrument via a replaceable rechargeable battery
or the mains unit provided (battery must be inserted).
With an attached mains unit, power is supplied automatically via the mains unit
and the rechargeable battery is charged (only at ambient temperatures from 0 to
40°C). Operation is possible with the mains unit connected.
It is also possible to charge the battery using a charging station (accessory).
The instrument is equipped with a buffer battery to maintain the system data
during an interruption in the power supply (e.g. when the battery is changed).

Detector may be damaged!
- Do not point the camera at objects with temperatures > 650 °C.
Ideal framework conditions
• Building thermography, investigating the building shell:
Considerable temperature difference between inside and outside required
(ideal: ≥ 15 °C / ≥ 27 °F).
• Consistent weather conditions, no intensive sunlight, no precipitation, no
strong wind.
• To ensure maximum accuracy, the camera requires an adjustment time of
10 minutes after it is switched on.
Important camera settings
• Emissivity and reflected temperature must be set correctly in order to
precisely determine the temperature. Subsequent adjustment is possible via
the PC software, if required.
• When auto-scaling is activated, the colour scale is continuously adjusted to
the min./max. values of the current measurement image. This means that
the colour assigned to a specific temperature is changing constantly! To be
able to compare multiple images based on the assigned colour, scaling must
be set manually to fixed values, or must be subsequently adjusted to uniform
values using the PC software.
5.1 Setting measuring functions
The submenu with the measurement settings opens:
• Pixel mark:
o Center spot: the temperature measuring point in the
centre of the image is marked with white crosshairs and
the value is displayed.
o Coldspot, Hotspot: the lowest or highest temperature
measuring point is marked with blue or red crosshairs and

• Differential temperature: identifies the difference between two
temperatures.

5.5 Setting emissivity and reflected
temperature
You can choose between user-defined emissivity and 8 materials with
permanently set emissivity. The reflected temperature (RTC) can be set
individually.
Other materials can be imported into the instrument from an existin
using the PC software.
Emissivity information:
The emissivity describes the capability of a body to emit electromagnetic
radiation. This is material-specific and must be adapted for correct
measurement results.
Non-metals (paper, ceramic, gypsum, wood, paints and coatings), plastics and
food have high emissivity, which means that the surface temperature can be
easily measured using infrared.
Because of their low or non-uniform emissivity, bright metals and metal oxides
only have limited suitability for infrared measurement. Highly inaccurate
measurements should be expected. A remedy for this is coatings that increase
emissivity, e.g. paint or emission adhesive (accessory: 0554 0051), which must
be applied to the object to be measured.

The following table gives typical emissivities of important materials. These
values can be used as a guide for user-defined settings.
Material (material temperature) Emissivity
Reflected temperature information:
Using this offset factor, the reflection is calculated out based on the low
emissivity, and the accuracy of the temperature measurement with infrared
measuring instruments is improved. In most cases, the reflected temperature is
identical to the ambient air temperature. Only when objects with strong
emissions at much lower temperatures (such as cloudless skies during outdoor
readings) or much higher temperatures (such as ovens or machines) are in
proximity to the object being measured should the radiation temperature of
these sources be determined and used. The reflected temperature has little
effect on objects with high emissivity.

5.7.2 SuperResolution
SuperResolution is a technology to improve image quality. For each shot a

PC software, an image is recorded with four times more measurement values
(no interpolation). The geometric resolution (IFOV) is improved by a factor of
1.6.
To use the function, the following conditions must be fulfilled:
