| 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. |

| 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 | |
| 06/17/13 | 07:58 | 536 | 1500 | -750 | 3.6 | 3.7 |
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?
Increasing Sense 10 volts at a time
