Calibrate the Rain Gauge
The rain gauge on the 5-in-1 sensor can be calibrated to improve accuracy.
Items Needed: 5-in-1 sensor, display unit, plastic cup, pin, screw driver
1. First, ensure 5-in-1 sensor is perfectly level using built-in bubble level.
2. Place display unit close so you can monitor it during calibration.
3. Make a pin hole in the bottom of a plastic cup. Hold the cup over the rain
gauge and fill it with exactly 1 cup (8oz) of water, allowing the water to
drip into the rain gauge. You should hear the internal buckets tip and see
water drain through the rain gauge.
4. A few seconds after each bucket tip, the display unit displays rainfall in
approximately 0.01" or more increments.
5. The cup of water should take more than 10 minutes to empty; a quicker
11
period will result in inaccurate calibration. Try to simulate a normal steady
rainfall. When cup is empty of water, display unit should register 1.06"
Tips
• There should be nearly an equal number of water drops (about 25 water
drops) between bucket tips. If not, adjust the calibration screws on the
bottom of the 5-in-1 sensor until an equal number of water drops are tipping
the buckets. Then, restart the calibration procedure.
• If you don't hear the buckets tipping and see water dripping alternately out
of each drain, there may be an issue with the rain gauge or it's adjustment.
See Troubleshooting on page 20.
Adjustment
If the rain gauge doesn't register close to 1.06", make an EQUAL adjustment to
the two calibration screws on the bottom of the 5-in-1 sensor. Turning screws
clockwise increases rainfall; counter clockwise decreases rainfall.
• To adjust the rainfall reading by 2% turn both screws 1/8 of a turn.
• To adjust the rainfall reading by 4% turn both screws 1/4 of a turn.
• To adjust the rainfall reading by 8% turn both screws 1/2 of a turn.
