6.2 Getting to know the product
6.2.1 Switching the instrument on and off
Switching on
Only switch on the instrument in fresh air, since automatic zeroing is carried out
when the instrument is switched on. The ambient temperature and ambient
humidity during zeroing should correspond to the ambient conditions at the
measuring location. If necessary, zero again manually at the measuring location
(switch off and on again).
If the unit is not used for a prolonged period of time, the sensor will
become contaminated. Particularly if the instrument has not been in
operation for a prolonged period of time (> 2 weeks), it should be left
switched on for a while before being used. The longer it has not been in
operation, the longer this additional warming-up phase should be.
Please note that the instrument switches itself off by default after 10
min of inactivity.
1
Press and hold down (1 sec) the On/Off key.
Warm-up phase (HEAT)
 
The instrument starts up. With regular use, the warm-up period takes
approx. 20 sec and is symbolized by the flashing and emptying bar
display.
As long as the sensor LED is flashing orange, the instrument is not
ready for use.
