Humidity Sensor Calibration
This function is only used if a new humidity sensor is installed. Press
select
and
humidity
hold
to enter this mode. The first number to appear is the voltage at
0% humidity that the sensor outputs. Press
select
again and a second number
will appear. This larger number is the voltage that the sensor outputs at 75%
humidity. The humidity calibration numbers are found on the
humidity/temperature sensor and on the back of the instrument console. These
calibration numbers are supplied to us by the manufacturer of the sensor and
are normally not changed.
