|---|---|---|---|---|---|
| 5581 | 2021-11-18 | Bouldin Corn Precipitation | Calibration | Bouldin Corn Precipitation | I adjusted the screw 1 turn CCW before testing b/c I forgot to adjust it after the previous test. We dripped 240ml of water through the bucket using a peristaltic pump powered with a lithium battery. This should result in 50 tips in about 20 minutes. We got 49 tips and I called it good until next year. |
| 5574 | 2021-11-05 | Bouldin Corn Precipitation | Tested | Bouldin Corn Precipitation | We dripped 240ml of water through the bucket using a peristaltic pump powered with a lithium battery. This should result in 50 tips in about 20 minutes. We got 52 tips but forgot to adjust the screws. |
| 5541 | 2021-10-21 | Bouldin Corn Precipitation | Tested | Bouldin Corn Precipitation | We dripped 240ml of water through the bucket using a peristaltic pump powered with a lithium battery. This should result in 50 tips in about 20 minutes. We got 54 tips and adjusted its set screws 1.5 turns CCW (1/2 turn of both screws is a 2-3% adjustment). |
| 5018 | 2020-12-03 | Bouldin Corn Precipitation | Tested | Bouldin Corn Precipitation | Plugged tipping bucket into the calibration CR23x and dripped 475ml of water through the bucket (1/2 of the bottle at a time) which should result in 100 tips. Got 117 tips. Did not adjust - will retest with better water metering system. |
