The preference set order is as follows:

OUTDOOR TEMPERATURE

OUTDOOR HUMIDITY

INDOOR TEMPERATURE

INDOOR HUMIDITY

BAROMETRIC PRESSURE (must be set to MANUAL mode to calibrate)*

*To change from AUTO to MANUAL pressure mode and vice versa, press AND

HOLD the "SET" button for at least 10 seconds. The display indicates the current

pressure mode selected,"AUTO" or "MANUAL".

After 20 seconds of inactivity, the display will save the adjustments and exit calibration

mode. Note: Calibrations will be erased if the display is reset or if 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 8oz (236 ml) 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" (.254 mm) 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" (26.92 mm).

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 18.

Adjustment

If the rain gauge doesn't register close to 1.06" (26.92 mm), 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.
