metric measurement adapter.
6. Insert the metric measurement adapter between the arms of the tipping bucket, with
solid side of the metric measurement facing up.
Although the rain collector is now ready to take accurate metric measurements, the
console does not register the rain collector measurement weight has changed. The rain
measurement type must be changed on the console.
Rainfall Calibration Number
Each station uses a rainfall calibration number (CAL) to determine how much water each
bucket tip (i.e., pulse) represents.
The default rainfall CAL of 100 works for the 0.01" rain collector. If you have a 0.01"
rain collector you do not need to adjust CAL at all.
