●
ERR 06 Max. calibration points exceeded
Explanation
Calibration was performed on a fourth calibration point.
This error does not affect calibration data obtained from previous three
calibration points.
Standard solution calibration" page 18.
●
ERR 07 Cannot identify standard solution
Explanation
If the automatic standard solution identification function of the meter
does not work, recalibrate the meter after performing the appropriate
measures below.
●
ERR 08 Calibration cycle error
Explanation
This error appears when the number of measurements set for the
calibration cycle has been exceeded since the last calibration was
conducted.
Calibrate again.
Cause
How to solve problem
Calibration was
performed on a fourth
calibration point.
Limit the number of calibration points to three.
This error message is cleaned by setting the
meter to Measurement mode.
Cause
How to solve problem
There is a problem
with the standard
solution.
Prepare new standard solution.
There is a problem
with the standard
solution setting.
Check the NIST or US standards settings and
the kind of standard
solution used for calibration, and make sure
they match.
The responsive
membrane is dry or
dirty.
Measure after washing the responsive
membrane and soaking it in pure (de-ionized)
water for 24 hours.
The reference solution
is contaminated.
Replace the reference solution with new
solution.
The responsive
membrane is damaged
or worn out.
Replace the electrode.
