Troubleshooting Guide

Rainfall is not registering on the console or the console has a large error.

• Check the cable connections from the sensor to the console. Cable connections

account for a large portion of the potential problems. Connections should be firmly
seated in the jacks and plugged in straight. If a reading appears intermittently on the
display as you jiggle the cable, the connection is faulty.

• Make sure there is no magnetic, steel, or iron object near the rain collector.
• Make sure the funnel hole in the cone is clear so water can empty into the spoons.
• Make sure the spoons move freely when tipping to both sides. The console should

show an increase in rainfall for each tip of the spoons. (If the spoons do not move at
all, check that you have cut the cable tie that holds them in place during shipping.)

• Make sure the rain collector is mounted so that it is level.
