DESCRIPTION AND USE OF CONTROLS AND INDICATORS FOR ULTRAMETER 6P
Press <CAL/MCLR> to enter calibration mode. The "CAL", "BUFFER" and "7" annunciators will
appear (see figure to the right). Displayed value will be the uncalibrated sensor.

NOTE: Attempted calibration of >1 pH point from factory calibration will cause "FAC" to appear. This indicates the
need for sensor replacement or fresh buffer solution. The "FAC" internal electronic calibration is not intended to
replace calibration with pH buffers. It assumes an ideal pH sensor. Each "FAC" indicates a factory setting for that
calibration step (i.e., 7, acid, base).
You can press <CAL/MCLR> to accept the preset factory value, or you can reduce your variation from factory setting
by pressing < /MS> or < /MR>.
Press <CAL/MCLR> to accept the new value. The pH Zero Calibration is now complete. You may
exit by pressing any measurement key.

TOTAL RETURN to FACTORY SETTINGS
"FAC SEL"
There may come a time when it would be desirable to quickly reset all the recorded calibration values in the instrument
back to the factory settings. This might be to ensure all calibrations are set to a known value, or to give the instrument to
someone else free of adjustments or recorded data for a particular application.
