3.6 Operation check
The correct operation of the module and the LC display can be verified as follows:
The “CONTROL”-switches must be in the upper position for manual control. For each channel turn the 10-turn potentiometer for
V
SET
by one revolution such that the number in vision panel shows “1” and the circular scale is in position “0”. This setting
corresponds to 10% of the nominal Voltage. I
SET
must be set to a value >10%. No cables are connected to the HV-output. After
switching on high voltage with the switch “HV-ON” the yellow LED turns on and a voltage of 10%±1% V
nom
is shown in the LCD. The
read LED (“ERROR”) must stay off and the displayed value for the current of the channel should be below 0.2% I
nom
.
