Technical data
General data
Error symptom
Cause
Remedy
No temperature or con-
ductivity display
– No connection between meter
and conductivity measuring cell
– Cable defective
– Establish connection between
meter and conductivity
measuring cell
Measurement delivers
implausible conductiv-
ity values
– Measuring range exceeded
– Contamination in the area of the
electrodes
– Electrodes damaged
– Make sure the correct sensor is
being used for the application
– Clean the conductivity
measuring cell (see section ).
– Return the sensor
Incorrect temperature
display
– The temperature sensor is not
immersed deep enough in the
measuring solution
– Temperature sensor defective
– Observe the minimum immersion
depth
– Return the conductivity
measuring cell
