● ERR No.0005 Electrode sensitivity error
Detected that the electrode sensitivity is out of the setting range that allows proper
measurement.
Cause
The electrode is dirty.
The electrode is cracked.
Calibration was not performed
correctly.
The electrode is not connected
correctly.
Electrode is not immersed
enough to cover liquid junction.
There is a problem with the
standard solution.
● ERR No.0006 Maximum calibration points exceeded
Attempted to perform 6th point calibration during pH calibration.
Cause
6th point calibration is
attempted.
● ERR No.0007 Cannot identify standard solution
Unable to automatically detect the standard solution during pH calibration.
Cause
There is a problem with the
standard solution.
Settings about the standard
solution do not match the
instrument.
The electrode is dirty.
The electrode is cracked.
The standard solution
concentration is fluctuating.
Electrode is not immersed
enough to cover liquid junction.
How to solve problem
Clean the electrode.
Replace the electrode.
Perform calibration correctly.
Connect the electrode correctly.
The electrode must be immersed up to the liquid junction.
As a guide, immerse to at least 3 cm from the tip of the
electrode.
Use new standard solution.
How to solve problem
Up to five points can be calibrated.
How to solve problem
Use new standard solution.
Check if the instrument settings and the specifications of
the standard solution are compatible.
Clean the electrode.
Replace the electrode.
Replace the internal solution in the reference electrode.
The electrode must be immersed up to the liquid junction.
As a guide, immerse to at least 3 cm from the tip of the
electrode.
