Carry out Rain Gauge tests as follows:
1.
2.
3.
Connect a DMM to measure resistance between the 6 Metre cable clear and
black wire connections.
If the unit is assembled slowly pour in water to see make and break
connections and momentary readings (of 47 ohms) in each tip direction.
If the unit is disassembled gently move the tipping bucket arm to the upright
position and read the DMM resistance between the clear and black contact
wires is close to 47 ohms. As the arm moves away from the upright position
to a rest position in either direction the resistance should change to Greater
than 1M ohms (open circuit).
