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.
