rH Calibration

4� Press [Target] to navigate to "Set Target rH"� Enter the relative humidity
reported by the reference instrument�
5� Press [Calibrate Offset]�
6� Verify that the message "in base cal" is displayed� This lasts about two
seconds�
7� Verify that the message "Calibration Done" is displayed�
8� Press [X]
9� Verify that the Current rH agrees with the reference hygrometer� Note that this
screen does not automatically update� If desired, an update can be forced by
exiting and re-entering this screen�

Factory Cal]
