2.1 Operation and maintenance advice
a.) Battery operation:
If BAT is shown in the left part of the display the battery has been used up and needs to be replaced.
However, the device will operate correctly for a certain time.
However, the device will operate correctly for a certain time.
The battery has to be taken out, when storing device above 50°C. We recommend taking out
battery if device is not used for a longer period of time.

b.) Treat device and sensor carefully. Use only in accordance with above specification. (do not throw, hit
against etc.). Protect from soiling.

3.4 Running measurements
a) Please pay attention that no dirt gets into the vents. If this has already taken place, please do not try to
remove it. Improper treatment can damage the sensors. Additionally the device should be saved from
mechanical agitation, because this can also damage the sensors (carrier material glass and ceramic)!
mechanical agitation, because this can also damage the sensors (carrier material glass and ceramic)!
Attention: In the sensor area the instrument is ESD-sensitive. Never touch or hold sensor head!
b) For fast measurements of ambient air: Hold device by the outstretched arm and sway back and forth (to
fan) to accelerate the air exchange and the temperature matching. As soon as the measured value is
quite stable, it can be read off.
quite stable, it can be read off.
It may make sense to press the hold key to “freeze” all values and
therefore read them off easily.
c) If the device is held in the hand during the measurement, both temperature and humidity are altered by the
body heat. To minimize this influences the device should be held as far away from the sensor as possible
and a direct contact with the exhaled air should be avoided. Most accurate measurements are achieved, if
the device is set down and the measured value (as soon as it is stable) is read at adequate distance.
