| 1450 | Made slight error when starting last night's data acquisition routine: selected 4 files at each bias rather than a single one. Therefore, interrupted data acquisition after data series 07140419_1435 for helium transfer. This data series was first at -/+3 V bias. No matter - more data is better than less data. Will resume data acquisition once helium transfer has been completed. |
| 1505 | Commence helium transfer. Helium liquid level 10.4%. |
| 1545 | Cease helium transfer. Helium liquid level 92.9%. |
