| 2018-07-11 | 49187-109 | TE525MM | Installed | Precipitation | Installed at Sherman Barn on a T-post in the northwest corner of the cow fence. This is the initial set up of the site. |
| 2018-10-18 | 49187-109 | TE525MM | Calibration | Precipitation | Got 94 of 100 tips - adjusted by a total of 3.5 turns CCW (screws were loose, so this total is suspicious; should have been a CW adjustment when all was said and done) 2018-10-18: Got 94 of 100 tips - adjusted by 0.5 turns CW. 2018-12-18: Got 117 of 100 tips - adjusted by 1 turn CCW, but screws feel very loose. 2019-01-03: Got 118 of 100 tips - adjusted by 3 turns CCW. (previous adjustment of 1 turn CCW did not seem to make a difference). 2019-01-24: Got 100 of 100 tips! No adjustments made. |
| 2019-10-31 | 49187-109 | TE525MM | Calibration | Precipitation | After cleaning the tipping bucket we connected it to a CR23x and dripped 475ml of water through the bucket which should result in 100tips. We got 90 tips. We turned its set screws two full rotations CW. |
| 2019-11-19 | 49187-109 | TE525MM | Tested | Precipitation | Plug tipping bucket into the calibration CR23x and dripped 475ml of water through the bucket which should result in 100tips. Got 104 tips and turned both set screws 1/2 turn CCW. |
| 2020-07-09 | 49187-109 | TE525MM | Removed | Precipitation | Removed from Sherman Barn with its decommissioning and given to Sabina of Hydrofocus. The DWR grant ended at the end of June 2020, and Bryan requested we hand off a tower to Hydrofocus. |
