batteries are removed and the power adapter is unplugged.

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, plastic cup, pin, screw driver

1. First, ensure 5-in-1 sensor is perfectly level using built-in bubble level.

2. Place display 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 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, display 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 15.

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.
