Rain reads low
Low rain readings indicate the rain sensor and Professional weather 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 Manual Tip Test and a Water Tip Test and compare them:
Manual Tip test: Write down the Total Rain reading or reset the Rain Total to 0.00.
Use the eraser end of a pencil to manually tip the rocker of the rain sensor 10 times
(five each way). Wait at least 2 minutes for all the rain to collect.
Water 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 (five each way). Wait at least 2 minutes for all the rain to
collect.
Compare these tests. If they are the same, then the 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 reads high
Check for sources of RF (radio frequency) interference such as other wireless
rain sensors, ham radios or electric transformers.
Keep the Professional weather station six feet from cordless phones or wireless
routers etc.
