Title: Calibration
Notes: 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.
