| Date | Time (24h) | Guard (V) | Sense (V) | Field (V) | Sense (A) | Field (A) | comments |
| 04/08/13 | 12:27 | 536 | 1100 | -750 | Tripped (trip is set to 10 A). Initially settled around 4-5 A. | ||
| 04/08/13 | 12:36 | 536 | 950 | -750 | Tripped | ||
| 04/08/13 | 12:40 | 536 | 850 | -750 | Fluctuating from 1.5-3.0 A on both sense and field. | ||
| 04/08/13 | 13:32 | 536 | 850 | -750 | Tripped | ||
| 04/08/13 | 13:40 | 536 | 800 | -750 | Set trip threshold to 15 A. Current tripped within 5 minutes. | ||
| 04/08/13 | 13:45 | 536 | 750 | -750 | Sense/field fluctuating around 1.5 A. | ||
| 04/08/13 | 14:40 | 536 | 750 | -750 | 2 | 2 | HV found in tripped state, set Imax to 100 A, and restored HV. |
| 04/09/13 | 07:34 | 536 | 750 | -750 | 0.1 | 0 | |
| 04/09/13 | 07:35 | 536 | 800 | -750 | 0.1 | 0 | |
| 04/09/13 | 07:35 | 536 | 900 | -750 | 0.2 | 0.3 | |
| 04/09/13 | 07:37 | 536 | 1000 | -750 | 1.5 | 1.6 | |
| 04/09/13 | 07:37 | 536 | 1050 | -750 | 6.2 | 6.3 | |
| 04/09/13 | 10:12 | 536 | 900 | -750 | 5 | 4 | 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 30A spikes at 900 Volts |
| 04/09/13 | 11:00 | 536 | 890 | -750 | 0.1 | 0 | Found HV in tripped state, set HV to 890 any further and 30 A current spikes occurr, changed trip time from 0.1 to 1.1 sec |
| 04/09/13 | 13:11 | 536 | 900 | -750 | 0.1 | 0 | current is jumping more |
| 04/09/13 | 13:11 | 536 | 890 | -750 | 0.1 | 0 | found HV in tripped state, went back to 890 |
| 04/09/13 | 17:22 | 536 | 890 | -750 | 0.05 | 0.00 | |
| 04/09/13 | 17:30 | 536 | 970 | -750 | 1.3 | 1.2 | 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 A for a few seconds. |
| 04/10/13 | 07:40 | 536 | 970 | -750 | 0.115 | 0.005 | Found fields in tripped state, but not sense or guard. Turned on again, current was relatively low. |
| 04/10/13 | 07:50 | 536 | 1080 | -750 | 1.1 | 1.0 | Went up in voltage in 10V increments at 1V/s ramp, monitoring change in average current at each step after voltage settled. Last increment to 1080 saw some surge currents up to 30 A, but average current is around 1 A. |
| 04/10/13 | 10:40 | 536 | 1070 | -750 | 0.2 | 0.3 | Found fields in tripped state. Set sense to lower voltage and reset field voltage. |
| 04/10/13 | 10:42 | 536 | 1070 | -750 | 1.3 | 1.4 | Tried turning voltage on sense up to 1080, current and voltage started fluctuating more than usual. Turned voltage back to 1070. Current is still a little higher than when initially started up again at 10:40, fluctuating from 1 to 4 A. |
| 04/10/13 | 11:04 | 536 | 1050 | -750 | 1.3 | 1.4 | Found Field & Sense HV in tripped state, set Sense HV to 1050 current becomes non zero after a sense wire Voltage of 1000 VOlts |
| 04/10/13 | 11:25 | 536 | 1050 | -750 | 0.2 | 0.3 | tried to increased to 1060 since current fluctuations were small and below 0.2 A, both sense & FIled tripped so returned to 1050 sense wire voltage setting |
| 04/10/13 | 12:30 | 536 | 1050 | -750 | 0.2 | 0.3 | |
| 04/10/13 | 13:45 | 536 | 1070 | -750 | 0.15 | 0.25 | Current instability was observed when taking voltage up to 1075. Backed off to 1040, current stabilized to less than 0.01 A. Raised back up to 1070V again, current appears stable for the moment. |
| 04/10/13 | 15:15 | 536 | 1070 | -750 | 0.065 | 0.115 | |
| 04/11/13 | 08:30 | 536 | 1120 | -750 | 0.065 | 0.115 | Currently raising voltage only 1-3 volts at a time and monitoring sense current for a few seconds before raising again. If sense current stays above 0.075 for more than a few seconds, run-away current instability will usually start-up again. |
