Clean Electrode
This error message indicates poor electrode
performance (oset out of accepted window, or
slope under the accepted lower limit). Often cleaning
the sensor will improve the pH electrodes response.
See pH Electrode Conditioning and Maintenance for
details. Repeat calibration after cleaning.
Check Electrode Check Buer
This error message appears when electrode slope
exceeds the highest accepted slope limit. You should
check your electrode and use fresh buer. Cleaning
may also improve this response.
Bad Electrode
This message appears if the cleaning procedure
performed as a result of the above two messages is
found to be unsuccessful. In this case it is advised to
replace the electrode.
Wrong Buer Temperature
This message appears if the temperature of the
buer is outside the dened buer temperature
range. The calibration buer solutions are aected
by temperature changes in a dened manner.
During calibration the instrument will automatically
calibrate to the pH value corresponding to the
measured temperature but display it to the value at 25 ºC. Immediately after
calibration the buer should read the value of the buer at the temperature
of measurement.
Note: Temperature limits will be reduced to actual sensor specications.
