| Rec No. | Date | Loc From | Title | Loc To | Notes |
|---|---|---|---|---|---|
| 5559 | 2021-11-04 | Mayberry Precipitation | Adjusted | Mayberry Precipitation | Tested tipping bucket - got 53/50 tips. Adjusted screws 1/2 turn out (CCW). |
| 5539 | 2021-10-21 | Mayberry Precipitation | Tested | Mayberry 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). |
| 5369 | 2021-07-06 | Lab none | Installed | Mayberry Precipitation | Installed at MB again after replacing the cable in the lab. |
| 5359 | 2021-07-02 | Lab none | Repair | Lab none | I replaced the spliced cable with a new cable, no splicing needed. The ring terminals I had were a bit too large for the screw terminals inside the bucket, so I cut off a portion of the ring to make it more like a spade terminal. |
| 5358 | 2021-06-22 | Mayberry Precipitation | Removed | Lab none | Removed from MB and brought back to the lab for repair. It had lots of tips even though there hasn't been any rain, probably because the spliced area of the cable was underwater. |
| 4122 | 2019-10-22 | Mayberry Precipitation | Calibration | Mayberry Precipitation | Initially, the ground wire at the data logger was broken. 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 109 tips. We turned its set screw to full rotations CCW. Retest on 10-31 got 102 tips - good enough. |
| 3767 | 2018-10-25 | Mayberry Precipitation | Tested | Mayberry Precipitation | Repaired chewed cable and tested with 475ml water. Got 100 tips. Did not adjust set screws. |
| 1901 | 2015-06-25 | Lab none | Installed | Mayberry Precipitation | Installed on a post along the boardwalk to the tower at Mayberry. |
| 1838 | 2015-05-12 | Sherman Island Precipitation | Removed | Lab none | Removed with the decommissioning of the Sherman Cow Pasture site. |
