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, companion unit, plastic cup, pin, screw driver
1. First, ensure 5-in-1 sensor is perfectly level using built-in bubble level.
2. Use compatible companion unit or AcuRite software to monitor during calibration.
3. Make a pin hole in the bottom of a plastic cup. Hold the cup over the rain gauge and
ll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 companion unit displays rainfall in
approximately 0.01” or more increments.
5. The cup of water should take more than 20 minutes to empty; a quicker period will result
in inaccurate calibration. Try to simulate a normal steady rainfall. When cup is empty of
water, companion 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.
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.
