Press select a fifth time, and the unit displays in the rainfall window: 0, 1, 2, or 3. 2 is the normal display. Press the maximum or minimum key to enter the proper number (see calibration

reference for more information).

Press select a sixth time; the unit will display in the rainfall window a reading ranging from .01 to .1. Press the maximum or minimum button to enter the proper number.

Press select a seventh time - the unit displays wind direction. Press the maximum or minimum key to enter the actual wind direction.

Press select an eighth time - the unit will return to the normal display mode.

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.
