The arrow key can be used to scroll between the display pages.The alarm threshold value for the integrated relay can be freely entered via the keys. In addition to the alarm threshold, the hysteresis can also be freely entered.The 4 to 20 mA analog output can be scaled freely or also allocated to one further parameter, e. g. g/m³.After entering the system pressure of the compressed air system and the reference pressure (atmospheric pressure), the sensor can also calculate back to the atmospheric dew point from the measured pressure dew point if desired.
