Relative Humidity Calibration after
Sensor Change
Syntax: FCRH
The transmitter asks and measures relative humidity and calculates the
calibration coefficients. This two-point adjustment needs to be performed
after a sensor change. Follow the more detailed calibration instructions
on page 73, but instead of the CRH command, use the FCRH command.
Example:
>fcrh
