3. Using Your Weather Station
Calibrating Temperature And Humidity
You can calibrate inside and outside temperature, inside and outside humid-
ity, as well as any extra temperature or humidity sensors you have transmit-
ting to Vantage Pro.
1. Select the variable to be calibrated.
See "Selecting Weather Variables" on page 20.
2. Press and release 2ND, then press and hold SET.
After a moment, the variable you've selected will begin to blink. Keep
holding the SET key until the Calibration Offset message appears in the
ticker.
Note:
The ticker displays the current calibration offset.
3. Press + and - to add to 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) and a minimum
offset of -12.8 (°F or °C). The variable will change value and the ticker will
show the offset you've entered.
4. When you are finished, press DONE to exit calibration.
Calibrate Wind Direction Reading
You can use this procedure to correct your the anemometer reading. This is
useful if the anemometer does not point North in your installation.
1. Check the current direction of the wind vane on the anemometer.
Compare it to the wind direction reading on the console. If the wind vane
is pointing south, for instance, the wind direction reading on the screen
should be 180°.
• If the wind direction reading is greater than 180°, subtract 180 from
the reading and subtract the amount of the offset from the wind
direction reading.
• If the wind direction reading is less than 180°, subtract the reading
from 180 and add the amount of the offset to the wind direction
reading.
2. Press WIND as necessary to display the wind direction in degrees.
3. Press and release 2ND, then press and hold SET.
The wind direction variable will begin to blink.
4. Continue holding the key until the CAL message appears in the ticker.
Note:
The ticker displays the current wind direction calibration value.
5. Press < or > to select digits in the anemometer's current reading.
6. Press + and - to add to or subtract from the anemometer reading.
7. Repeat steps 4 and 5 until you have entered the offset value from Step 1.
8. When you are finished, press DONE to exit calibration.
