What to do if...
No temperature display
and/or no conductivity
display
Measurement does not
function
Measurement provides
implausible measured
values
Cause
Remedy
– System setting incorrect
– Correct the system setting
– Temperature sensor or
conductivity sensor defective
– Return the conductivity sensor
Cause
Remedy
– Protective cap still on
conductivity sensor
– Pull off protective cap
– System setting incorrect
– Correct the system setting
Cause
Remedy
– Conductivity sensor heavily
contaminated
– Clean conductivity sensor
– Boundary field not
maintained
– The conductivity sensor must
be surrounded by a gap of at
least 5 cm at the base and
sides when measuring at the
electrodes. Otherwise, the cell
constant can change (see
section 4.2.2)
– Electrodes damaged
– Return the sensor
– System setting incorrect
– Correct the system setting
– Measuring range exceeded
– Make sure the correct sensor is
being used for the application
– The sensor was installed in
an armature and the
boundary field is not sufficient
– Set the cell constant to the
value of the installed state (if
known)
– If the cell constant of the sensor
in the installed state is not
known, set the measured value
to the nominal value of a
sample (see section
4.2 A
)
