14 Calibrating ammonia sensors
14.1 Notes
14.2 General information
The calibration of ammonia sensors is based on measurements in ammonia-
free test solutions.
14.2.1 Calibration methods for ammonia sensors
Zero-point calibration
This calibration method is used to determine the ammonia zero point.
An ammonia-free test solution (e. g. water) is needed as a reference.
14.2.2 Calibration default settings for ammonia sensors
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:
