The Calibration Check™ feature may flag diagnostic messages during a
calibration. As electrode aging is normally a slow process, substantial changes
from previous calibrations are likely due to a temporary problem with the
electrode or buffers that can be addressed easily. These messages are seen
in Standard and Basic modes.
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
This message 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.
Press CAL then press CLR. “CLEAR CALIBRATION”
will be displayed. Press CAL to exit calibration if you
want to keep old calibration data instead of clearing.
Press the CFM key. “CLEAR ALL” will be displayed
followed by “CAL DUE”.
