Why the DosimaX plus A (HV) shows increasing values without being irradiated?
Increasing values can be a normal behavior due to the high sensitivity of the electrometer.
Mechanical influence (shaking, tapping,..) on the cable, the detector or the plug result in a charge shift, which is detected by the electrometer.
Accordingly the electrometer will measure a reading which is shown in the display.
Please follow these steps for correct measurements:
Connect the sensor to the DosimaX plus base unit
Set up your measurement equipment (place RQA sensor in the beam,...)
Switch on the DosimaX plus base unit
Important: Do not touch or move the equipment until exposure is done
