7. Repeat steps 3-6 with a second and subsequent buffers.
When the ATC probe is connected, the meter will continually
adjust for temperature. Therefore the buffer values may vary
slightly from the nominal values because of temperature
variations.
It is good to standardize your meter using at least 2 buffers.
When the meter accepts the second buffer, it will briefly display
the percent slope associated with the electrode's performance
prior to returning to the Measure mode.
% S L OP E
If the electrode is within the range of 90-102%, the GOOD
ELECTRODE message will appear.
GOOD ELECTRODE
If the electrode is outside this range, the meter will display the
ELECTRDOE ERROR message, and will not return to the
Measure screen until the user presses enter.
E LECTRODE ERROR
The meter will permit the user to use an electrode outside the
recommended range, but the ERROR message will persist.
