| 1447 | Dial HV down to 0V and ground. |
| 1449 | Fill LN2 cold trap bath. |
| 1450 | Flash DCRCs 1,3 for 30 sec. |
| 1450 | Ok, looks like it didn't flash for 30 sec. I entered Miniflash ON/OFF time (s): 30/5, Flash duration (h):0.0083. I don't know why that wouldn't work but the sequence lasted for 1.5 minutes before I ended it. Is this a problem or will it just take longer to cool back down? |
| 1601 | Flash DCRCs 1, 3 for 5 sec to end the flashing sequence. When I ended it immediately, it didn't actually turn the LEDs off. Now temperature is dropping. |
