2018-10-18 65552-615 TE525MM Calibration Precipitation Got 94 of 100 tips - adjusted screws a total of 1.5 turns CW 2018-10-18: Got 94 of 100 tips - adjusted screws 0.5 turns CW 2018-10-25: Got 96 of 100 tips - adjusted set screws 1 turn CW. 2018-12-18: 102 tips - no adjustment.
2019-10-31 65552-615 TE525MM Tested Precipitation We tested the rain bucket but got 124 tips when we should have had 100. Spider webs on the tipper might have been the problem. The webs were cleaned out but it needs to be retested.
2019-11-19 65552-615 TE525MM Tested Precipitation Plug tipping bucket into the calibration CR23x and dripped 475ml of water through the bucket which should result in 100tips. Got 100 tips and did not adjust the bucket.
2020-11-12 65552-615 TE525MM Tested Precipitation Dripped 475ml of water through the bucket which should result in 100tips. We got 92 tips. We turned its set screws two full rotations CW. We tested it again with another 475ml of water and got 96 tips. We left it as is. This needs to be tested again. One tipper also seems faster than the other.
