Care & Maintenance

Display Unit Care

Clean with a soft, damp cloth. Do not use caustic cleaners or abrasives. Keep away from dust, dirt and moisture. Clean ventilation ports regularly with a gentle puff of air.

3-in-1 Sensor Care

Clean the Sensor

Clean with a soft, damp cloth. Do not use caustic cleaners or abrasives.

Insect Prevention

Insects may cause obstructions and interrupt data by nesting in or on the 3-in-1 sensor. To limit this problem, spray sensor housing with a household insect repellent. Note: Insect repellent should not be sprayed on the internal components or into the sensor. Consult insect repellent instructions prior to use.

Snow & Freezing Weather

The 3-in-1 sensor will not be damaged by freezing conditions.

Clean the Wind Anemometer

Remove foreign matter from the outside of the sensor for free movement of the wind anemom- eter. If needed, use a small amount of spray lubricant, clear silicone or graphite powder on the anemometer for improved movement. Note: Spray lubricant, clear silicone or graphite powder should not be sprayed on the internal components or into the sensor.

Calibration

The indoor / outdoor temperature and humidity readings, wind speed interval, and barometric pressure can be calibrated on the display unit to improve accuracy. Calibration can improve accuracy when sensor placement or environmental factors impact the data accuracy.

1.To access calibration mode, press AND HOLD the “-“, “SET” and “+“ buttons simultaneously for at least 5 seconds.

2.To adjust the currently selected (flashing) item, press and release the “-“ or “+“ buttons to calibrate the data value higher or lower from the actual reading.

3.To save your adjustments, press and release the “SET” button to adjust the next preference. The “” icon will remain illuminated next to calibrated values.

The preference set order is as follows:

OUTDOOR TEMPERATURE

OUTDOOR HUMIDITY

INDOOR TEMPERATURE

INDOOR HUMIDITY

WIND SPEED INTERVAL (30, 60, 90, 120, 150 or 180 minutes) 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 10 seconds of inactivity, the display will save the adjustments and exit calibration mode. Note: Calibration preferences will be erased if the display is reset or if batteries are removed and the power adapter is unplugged.
