Error messages and trouble shooting
51
The indicated value does not change/No response
The measured value is out of the measurement range
When the measured value is below the display range, Ur appears. When the measured value
is over the display range, Or appears.
Repeatability of the measured value is poor
Nothing appears when the power is turned ON
Cause
How to solve problem
The conductivity electrode is broken.
Replace the conductivity cell.
The conductivity electrode is not
connected correctly.
Connect the conductivity electrode properly.
The instrument is in HOLD state.
Cancel the HOLD state.
Instrument defect.
Consult your dealer.
Cause
How to solve problem
Sample is out of the measurement
range.
Use a sample within the measurement range.
The conductivity electrode cable is
broken.
Replace the electrode.
Cell constant is not set.
Set the cell constant.
Calibration is not performed or
performed incorrectly.
Perform calibration correctly.
Instrument defect.
Check as explained below.
Cause
How to solve problem
Effect of the sample solution.
Repeatability becomes poor as the conductivity
value of the sample changes over time.
The conductivity electrode is dirty.
Clean the conductivity electrode.
The conductivity electrode is broken.
Replace the conductivity electrode.
Cause
How to solve problem
Power is not supplied.
Insert batteries.
Battery polarity (+, ) is reversed.
Insert the batteries with the polarity (+, ) correctly
oriented.
Battery life is low.
Replace the batteries.
Instrument defect.
Consult your dealer.
