To exit the humidity calibration mode at any time, press the
SNOOZE/LIGHT button on the top of the display console. If no
operation is performed, the calibration mode will timeout in 30
seconds.
Note: The Humidity is a difficult parameter to measure
accurately and drifts over time. The calibration feature allows
you to zero out this error. To calibrate humidity, you will need
an accurate source, such as a sling psychrometer or
Humidipaks One Step Calibration kit.
