9.2 Calibration of Humidity Mode
In normal mode, press and hold the SET and MAX/MIN/- keys
at the same time for five seconds to enter into the humidity
calibration mode. The indoor humidity will begin flashing.
Press the CHANNEL/+ key or MAX/MIN/- key to increase or
decrease the humidity reading (in increments of 1%). Press
and hold the CHANNEL/+ key or MAX/MIN/- key for three
seconds to increase or decrease rapidly.
Press the ALARM key to reset current value.
Press the SET key switch to outdoor humidity calibration
mode.
To exit the humidity calibration mode at any time, press the

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.
