measuring range
exceeded

Wrong signal

Temperature above 140°C not allowed.
Choose right measuring range for
conductivity

Err.2

Measuring value below
measuring range

Wrong signal

Temperature below -5°C not allowed.
Choose right measuring range for
conductivity

Err.7

System fault

Error in device

Disconnect from supply and reconnect.
If error remains: return to manufacturer

Err.9

Sensor error

Sensor or cable defective Check sensor, cable and connections

Er.11

Calculation not possible

Calculation variable
missing or invalid

Check temperature

8.8.8.8

Segment test

The transducer performs a display test for 2 seconds after power up.
After that it will change to the display of the measuring.
