Calibrating, Setting, and Clearing Variables

Calibration

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, inside and outside
humidity, as well as any extra temperature or humidity sensors you have
transmitting to Vantage Pro.
1. Select the variable you'd like to calibrate.
2. Press and hold the SET key.
After a moment, the variable you've selected will begin to blink. Keep
holding the SET key until a message appears in the ticker saying "cali-
bration offset 0".
3. Use the "+" and "-" keys to add or subtract from the variable's value.
Inside and outside temperature are calibrated in 0.1 ˚F or 0.1 ˚C incre-
ments, up to a maximum offset of +12.7 (˚F or ˚C) and a minimum off-
set of -12.8 (˚F or ˚C). The variable will change value and the ticker will
show the offset you've entered.
4. Press DONE to exit calibration.
• Calibrating wind direction,
1. Press WIND twice so that the wind direction is displayed.
2. Press and hold the SET key.
The wind direction will begin to blink. Continue holding until "Cal 0"
appears in the ticker.
3. Use the "+" and "-" keys to add or subtract from the variable's value. Use the
LEFT and RIGHT arrow keys to move between the hundreds, tens, and ones
places in the wind direction readout.
4. Press DONE to exit calibration.
The next time you enter wind direction calibration, the ticker will dis-
play the current offset.
• Calibrating barometric pressure
First, make sure that you've already entered the correct elevation in setup
mode.
1. Select the barometer by pressing BAR.
2. Press and hold SET.
The pressure variable will blink. Keep holding SET until the ticker
reads "set barometer...".
3. Use the "+" and "-" keys to add or subtract from each digit's value. Use the
LEFT and RIGHT arrow keys to move between the digits in the pressure read-
out.
4. Press DONE to exit calibration.
