9. Errors
If the instrument can not calibrate properly it indicates the following error:
-AIr
- generator voltage too low
AIr
- generator voltage too high
In such case power off the device, check the geometry of the electrodes, clean the
electrodes, make sure the device is dry and then start the calibration again (see chapter 4).
If the instrument still reports error contact the producer.
10. Changing the battery
The device is equipped with a power level control circuit. When the power drops
below acceptable level a sign ”LO BAT” appears on the left side of the LCD. This
indicates that the battery has expired and should be replaced with a new one.
To replace the battery unscrew the screw on the back of the instrument and carefully
remove the back panel.
Store the device in a dry place.

NOTE:
"This instrument doesn’t have ATEX protection, so it should not be used in potentially explosive
atmospheres (powder, flammable gases)."
