WARNING!
During the calibration, the relays and analog output signals assume the states
configured for the calibration! The response of the output signals is set for each
output in its "Response at calibration" configuration point.

The calibration of ammonia sensors is based on measurements in ammonia-
free test solutions.
This calibration method is used to determine the ammonia zero point.
An ammonia-free test solution (e.g. water) is needed as a reference.
In the ammonia sensor calibration default settings, the zero-point calibration is
enabled and preconfigured as the only available calibration routine.
Open the calibration default settings:
