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 30 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 Gauge mounted slowly pour water into the funnel to tip the rocker of the
rain sensor 10 times (five each way). Wait at least 30 minutes for all the rain to
collect.
Compare these tests. If they still read high, or low, then contact support.
Please provide the firmware version of the display (remove the batteries,
reinsert batteries and the firmware version - 222, 332, etc. will display in the
lower left corner).
Please provide the exact model of the TH sensor (TX59U-IT or TX59UN-1-IT).
If the tests read low, dismount the rain gauge and retest. One of the most
common problems with low rain is that the gauge is mounted too tight.
Check that the pin the rocker tips on is pushed in all the way and that the
rocker tips freely.
Check the funnel and inside of Rain Gauge for insect nests or debris that may
cause lack of motion.
Check for sources of RF interference such as Ham radio electric
Transformers, or other rain gauges nearby. In the house look to see if the
Display is near a cordless phone or wireless router etc.
