Rain Gauge Check and Clean Instructions
It is important to check the Rain Gauge at least every 3 months to ensure that it does not get
clogged with debris in the following places:
1. The funnel hole that funnels rain to the sensor inside the canister.
2. The drain holes that drain water after it has been measured.
Funnel Hole at Top of Rain Gauge
The Rain Gauge funnel will collect debris, such as: leaves, twigs, seeds, bird droppings, etc.
These items may accumulate and clog the funnel hole or limit the amount of rain that is
collected, causing little or no rain to be measured. All debris should be removed from the
funnel periodically. The best way to unclog the funnel hole is to take a narrow/pointed object
such as a toothpick or a paperclip and gently remove the clog from the hole. If the clog cannot
be removed from above, then you will need to remove the four or five screws to lift off the
cover so you can poke the clog out. Please be careful, as there are sensitive parts inside the
case that can be easily damaged. If it has not rained for some time, spider webs and bug
residue may need to be removed as they prevent the free movement of the tipping bucket
sensor.
Drain Holes in Bottom of Rain Gauge
If water does not drain from inside the Rain Gauge, it will collect inside the Rain Gauge and
the sensor inside may start floating and report more rain than the amount that actually fell.
Caution: Clearing drain hole clogs can cause you to get wet if the Rain Gauge is full of
water. Unclog the drain holes by poking a toothpick or paperclip up through the drain holes. If
this is not working, then remove the Rain Gauge cover as described above. Look for debris or
mold/mildew clogging the holes. Again please be careful, as there are sensitive parts inside
the case that can be easily damaged.
Testing the Rain Gauge
After you unclog the Rain Gauge, please test it to make sure it is reading correctly. To do this,
pour 8oz of water into the gauge. If the gauge is working properly, it should read 0.33 to 0.40
inches of rain. It is very important you make sure to pour the water into the Rain Gauge at a
slow, even pace. Pouring the water in too fast can cause inaccurate data.
Final Steps
Please ensure the Rain Gauge cover is securely fastened and that the Rain Gauge is securely
fastened to a mast that is secure. Masts that shake or sway are likely to record excessive
rainfall on windy days, even if it is not actually raining. To fix this problem, the mast should be
installed as securely as possible, and the Rain Gauge should be installed lower on the mast.
The Rain Gauge should be approximately 5 feet above the roof or ground and should NOT be
located directly beneath the Temperature Sensor.
