| 2010-09-02 | 24875-999 | TR-525I-R1 | Removed | Precipitation | This tipping bucket was removed from the Vaira tower to troubleshoot a problem that was causing the total number of tips not to be saved in the final storage location. |
| 2010-09-10 | 24875-999 | TR-525I-R1 | Installed | Precipitation | Reinstalled on the Vaira tower after testing in the lab. The testing revealed that the problem was a bug in the data logger program that was recording instantaneous values instead of 30min averages. |
| 2018-10-17 | 24875-999 | TR-525I-R1 | Calibration | Precipitation | Got 78 of 100 tips - adjusted screws 3 turns CW |
| 2019-10-24 | 24875-999 | TR-525I-R1 | Calibration | Precipitation | I connected the tipping bucket to a CR23x and dripped 475ml of water through the bucket which should result in 100tips. We got 103 tips. I did not adjust it. |
| 2021-10-06 | 24875-999 | TR-525I-R1 | Calibration | Precipitation | Tested using our new method with the peristaltic pump and 237ml of water which should result in 50 tips. I got 54 tips. I adjusted the screws two full turns CCW which should decrease the number of tips by 8-12% (4-6 tips). |
