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 “-“, “ ” and “+“ buttons simultaneously
for at least 5 seconds.
2. To adjust the currently selected (fashing) 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 “ ” 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 “ ” 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.
