Digital interface

The HCD probe has a UART interface with an logical level of 2.5 V

Modbus

Measurement values and serial number can be read out if the probe is to be used out of the RMS - please see Modbus

Adjustment

•1-point or multi-point humidity adjustment/calibration

•1-point or 2-point temperature adjustment/calibration

•Output the last adjustment/calibration, with date

•Produce an adjustment/calibration log

Sensor alarm

The probe outputs a digital alarm if the sensor has a short circuit or open circuit. This function cannot be deactivated.
