Rain reads OFL
OFL indicates that the weather station is receiving a signal from the transmitter.
The weather station will read OFL if it has counted more inches of rain (from testing, etc.) then it is
designed to read. Last week/last month rain 0 to 787.3 (0 to 9999 mm) 1-hour, 24-hour, yesterday
rain 0 to 78.73” (0 to 999.9 mm). Check for sources of
interference
such as other wireless rain
transmitters, Ham radios, or large electrical transformers. This may cause rain to add up when there
is no rain.
Check
batteries
in the rain transmitter and the weather station. This is our primary warranty issue.
Rain transmitter drains batteries quickly
If
batteries
are good when first inserted, batteries should last one year or more. If the batteries in the
transmitter are not lasting that long, please try these tips:
Test a new set of Alkaline batteries. Write down the date of installation and the voltage of the
batteries.
When the batteries fail, please note the date and voltage again. This is helpful in determining the
problem.
Complete the
restart
and confirm that everything is working after a battery change.
Battery leakage may cause a transmitter to drain batteries quickly.
Rain area on the weather station shows blank (no numbers or dashes)
Check that other areas of the weather station read properly. There may be a problem with the
weather station.
Rain reads low
Low rain readings indicate the rain transmitter and weather station are connected.
Check that the pin the rocker tips on is all the way to the back and that the rocker tips freely.
Check the funnel and the inside of the rain transmitter for insect nests or debris that may cause loss
of rocker motion.
Check for proper battery installation.
Check the battery cover is on firmly.
Be sure to mount the rain transmitter level and that the
mounting screws are not too tight
(most
common issue).
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 transmitter 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
Transmitter mounted, slowly pour water into the funnel to tip the rocker of the rain transmitter 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.
Check
batteries
in the rain transmitter and the weather station. This is our primary warranty issue.
Rain reads high
Check for sources of RF (radio frequency)
interference
such as ham radios, electric transformers, or
other rain transmitters nearby.
Keep the weather station six feet from cordless phones or wireless routers etc.
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 transmitter 10 times (five each way).
Wait at least 2 minutes for all the rain to collect.
