Calibrating, Setting, and Clearing Variables
25
Press 2ND and then press TIME to toggle the screen between the current time
and date or the sunrise and sunset times for the current day.
Note: See “Screen 4: Time & Date” on page 12 to change the console time and date or to select a 12-
or 24-hour clock.
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 & outside temperature, inside & outside humidity, as
well as any extra temperature/humidity sensor readings you have transmitting
to your Vantage Pro2.
1. Select a variable to be calibrated. See “Selecting Weather Variables” on
page 18.
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 ticker.
The ticker displays the current calibration offset.
3. Press the up or down arrows 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) and a minimum offset of -12.8
(°F or °C). The variable will change value and the ticker will show the off-
set you’ve entered.
4. Press DONE to exit calibration.
Calibrate Wind Direction Reading
You can use this procedure to correct 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.
