When an error message appears
48
●
ERR No.0003 Electrode stability error
Detected an electrode error because the electrical potential does not stabilize after 3 or
more minutes during measurement or calibration.
●
ERR No.0005 Electrode sensitivity error
Detected that the electrode sensitivity is out of the setting range that allows normal
measurement.
●
ERR No.0009 Printer error
An error occurred during printer communication.
Cause How to solve problem
The stability of electrode is
affected by the sample solution.
Read the value without using the automatic hold function.
The electrode is dirty. Wash the electrode.
The electrode is cracked. Replace the electrode.
The temperature of the sample
solution is fluctuating. Measure the sample solution after its temperature
stabilizes.
Cause How to solve problem
The electrode is dirty. Wash the electrode.
The electrode is cracked. Replace the electrode.
The stirring is inappropriate. Stir at an appropriate stirring speed (1000 to 1500 rpm).
The electrode is not connected
correctly
Connect the electrode correctly.
The settings are wrong.
Set the correct salinity correction, air pressure correction,
and temperature.
There is liquid on the DO tip
membrane. (when performing air
calibration) Let the electrode sit until the liquid evaporates or remove
the liquid using cotton gauze making sure not to scratch
the membrane.
There is something wrong with
the standard solution. (when
conducting standard solution
calibration)
Prepare new zero standard solutions.
Sufficiently bubble the span standard solution with a
diffuser or other tools.
Cause How to solve problem
There is a problem with the
printer unit connection. Check the printer connection, and connect the instrument
and printer again.
