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.
