Adjust Pressure Measurement
Use the CP command to perform an offset correction to the internal
pressure measurement. The correction is done by providing the correct
pressure as an argument to the CP command.
CP [pressure]
CP [-reset]
where
pressure = Correct pressure in hectopascals (hPa).
Example (adjust the internal pressure measurement to 990 hPa at the
current conditions):
pass 1300
cp 990
OK
Example (clear the offset adjustment from internal pressure
measurement):
pass 1300
cp -reset
OK
