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. If the unit is in protect mode this function is disabled.
