| 1319 | Flip LED switch SW2 on DCRC33 to '7B' side to switch the polarity. |
| 1326 | Stop flashing DCRCv1 G9 flashing. |
| 1329 | Plug DCRC33 to G9 |
| 1332 | Flashing still didn't work |
| 1337 | Flip SW2 to dot side and both SW1 and SW3 to '7B' side on DCRC33 |
| 1340 | Put it back on G9, flashing still didn't work |
| | Flip SW2 to '7B' side again |
| | 0X30 Bit 4, 0 is free run and 1 is single step |
| | DCRCv3, G9, LED1, -0.4mA, 100us on, 2500us off, temperature went up to 3K when flashing continuously. It is different from DCRC v1. |
| 1404 | Tried LED 2 with the same settings. LED 2 had the same behaviour. |
| | It seemed the LED driver output too much power. |
| 1454 | Switch to the old firmware and try the flashing function |
| | The old firmware did the same. Switch to the new one again. |
| 1654 | Fill N2 cold trap full. |
| 1741 | Try the zap vi |
| 1751 | 'zap all' produced a temperature spike from 60mK to 70mK. Zapping function worked. |
| 1757 | 'zap A' worked |
| 1824 | Transferred liquid He. |
| | 'zap c' and 'zap d' worked after a correction to a typo. |
| | Can not get charge signals on DCRC v3. The phonon signals are also small. The brass screws do make sqA and sqD work better, comparable to B and C. |
| 2305 | Bake G8 with DCRC v1, 400uA, 100us on, 2500us off. Tower temperature went up to 830mK. |
