Potentiometer settings (all are pre-adjusted!):
Zero point conductivity measurement
Range conductivity measurement
Setting for temperature measuring at 0 °C (Pt 100 = 100.0 Ohm)
Setting for range, e.g. at 95 °C (Pt100 = 136.8 Ohm)
DIP switch settings: S1 S2 S3 S4 S5 S6 Sensor required
Measur. range 0 – 20 with TC off on on off off ** K = 0.1, Pt100
Measur. range 0 – 20 without TC off on on off on ** K = 0.1
Measur. range 0 – 200 with TC on off off on off ** K = 0.1, Pt100
Measur. range 0 – 200 without TC on off off on on ** K = 0.1
Measur. range 0 – 2000 with TC on off on on off ** K = 1.0, Pt100
Measur. range 0 – 2000 without TC on off on on on ** K = 1.0
For DIP switch position S5: ** For DIP switch position S6:
With Temp. compensation: bottom Relay triggered at conductivity < limit value: on
Without Temp. compensation: top Relay triggered at conductivity > limit value: off
Only one power supply connection is permitted; either 230 V AC or 24 V DC. The 24 V DC input
is protected against voltage reversal. AC voltage at the 24 V DC input oder DC voltage at the
230 V AC input destroy the instrument immediately and completely.
The measuring cell connection cable must be a shielded type for usage in industrial
environments at lengths above 1 meter.
The terminals ground and shield are internally connected to the common housing ground
(Voltage isolation of 1000 V to the power transformer and to the 24 V DC connection,
respectively). Under no circumstances these terminals should be bridged to another terminal
or connected to an existing ground connection. Otherwise the potential isolation of
measuring cell and electronics will be overruled.
6. Further operating conditions
The operation of the measuring instrument above the permitted measuring range and constant
short-circuit, respectively, can lead to instrument damage!
