Communication
A printer can be connected to the RS232 interface for print out of measured values. The values of
the conductivity or temperature are given out at the serial interface seperated by a comma.
Automatically the conductivity is scaled to three significant places. Output is made 1x per hour.
When the system is in operation mode a press on the “down” button triggers a measured value
output at the serial interface.
Print out example: 18.2 MΩ·cm, 23.4°C
Potential-free contact
The system is equipped on the systems panel with a potential free contact for control external
equipment. The maximum connected load is 30V, 2A
The Pin assignment of the 5 pin socket is:
