HV found in tripped state, set Imax to 100 [math]\mu[/math]A, and restored HV.

Found HV in tripped state, restored sense to 900 instead of 1050, it first tripped when attempting 900 Volts but staged 50 volts increases brought it back without tripping, I observe 30[math] \mu[/math]A spikes at 900 Volts

Found HV in tripped state, set HV to 890 any further and 30 [math]\mu[/math]A current spikes occurr, changed trip time from 0.1 to 1.1 sec

Changed voltage in steps of 10V at a time. Changed ramp rate to 1V/s on sense. Observed some surge currents after voltage stabilized at around 30 - 40 [math]\mu[/math]A for a few seconds.

Found fields in tripped state, but not sense or guard. Turned on again, current was relatively low.
