Wrong Buffer
This message appears when the difference between the pH reading
and the value of the selected buffer is too great. If this error message
is displayed, check if you have selected the proper calibration buffer
and have poured the desired buffer.
Wrong Old Points Inconsistency
“WRONG OLD POINTS INCONSISTENCY” is displayed if the new
calibration differs significantly from the last value of that sensor in
that buffer. In this case it may be best to clear the previous calibration
and attempt a new calibration with fresh buffers.
To clear calibration information, press CAL/MODIFY key then
press SETUP/CLR key. The “CLEAR CALIBRATION” message will be
displayed. Either press the GLP/CFM key and clear all calibration
information or press CAL/MODIFY key to exit to keep old calibration
data instead of clearing.
Once calibration information is cleared, the message “CAL DUE” will
be displayed
Clean Electrode
“CLEAN ELECTRODE” indicates poor electrode performance (offset
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 Buffer
“CHECK ELECTRODE CHECK BUFFER” appears when electrode slope
exceeds the highest accepted slope limit. You should check your
electrode and use fresh buffer. Cleaning may also improve this
response.
