When an error message appears
88
●
ERR No.0002
Empty battery level
The instrument cannot operate properly because the battery level is empty.
●
ERR No.0004
Asymmetric potential error
Detected that the asymmetric potential of the electrode is out of the setting range that
allows proper measurement.
●
ERR No.0005
Electrode sensitivity error
Detected that the electrode sensitivity is out of the setting range that allows proper
measurement.
Cause
How to solve problem
The battery level is empty.
Replace the batteries or connect the AC adapter (option).
Cause
How to solve problem
The electrode is dirty.
Clean the electrode.
The electrode is cracked.
Replace the electrode.
The standard solution
concentration is fluctuating.
Replace the internal solution in the reference electrode.
The electrode is not connected
correctly.
Connect the electrode correctly.
Electrode is not immersed
enough to cover liquid junction.
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.
There is a problem with the
standard solution.
Use new standard solution.
