Calibrating the chlorine sensor
Calibration should only be performed by an expert and is only accessible in Expert Mode.
Once the sensors have been connected, every input must be calibrated during initial start-up. Calibration is
necessary even if an electrode is replaced by a new one. The WATERFRIEND checks the calibration
procedures for plausibility during the process (slope and offset). Non-calibrated and "badly" calibrated
measurement inputs are displayed in plain text.
Time delays occur due to the electrode start-up times when the device is switched on.
