Calibrating, Setting, and Clearing Variables
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 begins
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.
