A. Calibration Edit
The calibration edit feature allows you to edit a pH or concentration
calibration curve without repeating the entire procedure. This is useful in
multipoint calibrations if an entry mistake was made on one of the points.
The meter will automatically recalculate all calibration values. There are
two options in the
cal edit function: Remeasure or Edit .
Remeasure allows you to remeasure a particular calibration point by
placing electrode(s) in the standard (or buffer), then entering the
correct value.
Edit has two choices: change or delete. Select change if a data entry error
was made, but electrode(s) were in the correct standard at the time of
calibration. Delete removes that point from the calibration curve.
Cal edit presents all calibration points in memory for editing. Respond to
the prompts and edit as needed. Cal edit may be performed for both pH and
ISE calibrations.
If no previous calibration has been performed the meter will prompt, NO
CALIBRATION, then return to MEASURE mode. Otherwise, follow the
prompts to edit the calibration. The example provided here uses a
concentration calibration. A pH calibration would substitute the word
BUFFER for STD.
