Calibrating, Setting, and Clearing Variables
Your Vantage Vue weather station is factory-calibrated and tested to be highly accurate. You
should not need to calibrate it. However, to fine-tune your station, you can calibrate most of
the weather variables. For example, if your outside temperature seems consistently too high or
too low, you can enter an offset to correct the deviation.
Calibrating Temperature and Humidity
You can calibrate inside and outside temperature, and inside and outside humidity on your
Vantage Vue.
1. Select the temperature or humidity variable to be calibrated.
2. Press and release 2ND, then press and hold SET.
After a moment, the variable you’ve selected will begin to blink.
Keep holding SET until the Calibration Offset message displays in
the Weather Center.
3. Press the + or - keys to add or subtract from the temperature offset value.
Inside and outside temperature are calibrated in 0.1° F or 0.1° C increments, up to a
maximum offset of
+
/ - 12.7 (°F or °C). The variable’s value will change and the Weather
Center shows the offset you have entered.
4. Press DONE to exit calibration.
Calibrating Wind Direction Reading
The wind vane on your ISS is calibrated at the factory to be accurate when the solar panel
above it is pointing south. If your solar panel does not point south, you must use this procedure
to correct the wind direction. In any case, you can also use this procedure to fine-tune your
station for greatest accuracy.
Note: Wind direction calibration should be done when the ISS is mounted in its final position and
the vane is still.
1. With the wind vane stationary, ascertain its actual direction. Compare it to the direction
reading on the console.
2. Press WIND until the wind direction in degrees is displayed.
3. Press and release 2ND, then press and hold SET. The wind direction variable will begin to
blink.
4. Continue holding SET until “CAL” displays in the Weather Center. The Weather Center
displays the previously set wind direction calibration value, if one has been set.
5. Change the value of the wind direction in the compass rose
based on the direction the anemometer is currently pointing.
Due north is 360°, east is 90°, south is 180° and west is
270°.
6. Press the < and > keys to select digits in the anemometer’s
current reading.
7. Press the + and - keys to set the correct reading.
8. Press DONE to exit calibration.
Note: Wind direction can not be corrected by repositioning the wind vane.
