Date Time (24h) Guard (V) Sense (V) Field (V) Sense ([math]\mu[/math]A) Field ([math]\mu[/math]A) comments
05/28/13 14:08 100 100 -100 0.02 0.00 Confirmed with initial setting of 30/40/50V that there are no crossed connections between wire types and that voltage supply is connected correctly.
05/28/13 16:34 536 1500 -750 45.5 45.5 Someone upped the voltage to full the full operating level without recording it. This is the current reading right now.
05/28/13 17:56 536 1500 -750 41.5 41.6
05/29/13 07:56 536 1500 -750 22.5 22.6

06/05/13 12:01 536 1500 -750 1.8 1.9 had to turn off HV to organize cables
06/05/13 17:56 536 1500 -750 1.8 1.9
06/06/13 07:56 536 1500 -750 1.8 1.9 seem to be stuck at this current draw?
06/10/13 17:29 536 1500 -750 1.5 1.6 I think we ran out of gas on the weekend, the windows were deflated a bit but now they deflected outward
06/11/13 07:50 536 1500 -750 3.2 3.3 current doubles? Humidity dropped from 40 to 25%.
06/12/13 13:39 536 1500 -750 3.6 3.7 Humidity rose from 25 to 40%.
06/13/13 11:00 536 1500 -750 4.5 4.6 Humidity is 40 +/- 5 %.
06/14/13 08:56 536 1500 -750 3.5 3.6

Why is the current increasing?

is the current going to ground ?

Try raising the sense to 1750 and lowering the field to 500 (same voltage difference), and see if the sense current still equals the field current - want to know if the current is inside the chamber from wire to wire or if it's a current to ground, for example ...

==If current is from field to sense:

if it is current from field to sense the current should increase exponentially with voltage, doubling with 100V increase; i.e. 2250 -> 2350. You could check to see if this is the case. If so, you could then try to locate where the problem is: which wire(s) are responsible?
