RAIN LOW: WHY IS MY RAINFALL READING LOW?

• Low rain readings indicate the rain sensor and station are connected.
• Check that the rocker tips freely.
• Check the funnel and the inside of the rain sensor for insect nests or debris that may cause
loss of rocker motion.
• Be sure to mount the rain sensor level.
Complete a Tip Test:
Write down the Total Rain reading or reset the Rain Total to 0.00. With rain sensor mounted
slowly pour water into the funnel to tip the rocker of the rain sensor 10 times. Wait at least 2
minutes for all the rain to collect. Repeat three times.
• Compare these tests. If they are the same, then your rain is reading correctly. If the rain
readings are different, repeat the test 3 times to avoid human error. Then look for causes
such as mounting too tight or debris clogging the funnel.

RAIN HIGH: WHY IS MY RAINFALL READING HIGH?

• Check for sources of RF (radio frequency) interference such as other wireless rain sensors,
ham radios or electric transformers.
• Keep the station six feet from cordless phones or wireless routers etc.
Complete a Tip Test:
Write down the Total Rain reading or reset the Rain Total to 0.00. With rain sensor mounted
slowly pour water into the funnel to tip the rocker of the rain sensor 10 times. Wait at least 2
minutes for all the rain to collect. Repeat three times.
• Compare these tests. If they still read high then contact support.
1. Remove rain funnel (open locking tabs on both sides and pull off funnel)
