Calibrating, Setting, and Clearing Variables
28
1. Select a variable to be calibrated. See “Selecting Weather Variables” on
page 21.
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 Off-
set 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 off-
set 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.
Calibrate Wind Direction Reading
You can use this procedure to correct the anemometer reading. This is use-
ful 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.
4. The wind direction variable will begin to blink.
5. Continue holding the key until the CAL message appears in the ticker.
Note:
The ticker displays the current wind direction calibration value.
6. Press the right or left arrows to select digits in the anemometer’s current
reading.
7. Press the up and down arrows to add or subtract from the anemometer
reading.
8. Repeat steps 4 and 5 until you have entered the offset value from Step 1.
9. Press DONE to exit calibration.
