| 0525 | Feed cat breakfast. Birds woke her up. |
| 0532 | Start a 90 min series at HV = 180→400V, rate 2.418V/min with 10% prebias for 2 minutes, flash at end with 30 min wait. CDMS detector: Driver Gains = 1x, DCRC4/1 QET biases = (490/400/490)/(420/480/450) uA, Front-End Gains = (2/2/3)/(5/5/5) 1000 BOR, 5Hz InRun, and 1000 EOR randoms, trigger on DCRC1pB/C/D threshold = 6/6/6. Use sequence HVdrift_180V_cal0612_2p418VPM_prebias_10_2_dur_90min_flashDCRC_1_4.msl |

| 1930 | Looks like DCRC1pD was railed for the last entire sequence. |
| 1945 | Adjust DCRC1pD driver offset to unrail it |
