Kicker test Nr 1
Dear all,
I just excchanged the suspicious card DN-13 in cabinet HV1 with a spare
card. I then switched the kicker on with the constant kicking of 5mus at
1kHz. All yellow LEDs working fine. I first ramped the upper plates,
that is the HV on HV2 without problems to 8kV (all red LEDs visible)
with practicall no current (<0.2mA). I switched off this side and ramped
HV1 very slowly. At 0.4 kV there was already a current of several mA
which increased when going to 0.7 kV. At this voltage I couldn't yet see
the red LEDs on the lower stack but I think it's not necessary to test
that since the high current is unusual for normal behaviour.
Therefore, the spare card didn't help. Together with Brendan, I will do
the proposed tests after lunch. We'll use a DC mode when removing this
plug. In case we are not sure about some step we'll try to contact you,
Mike via phone.
Greetings
Peter
