Single-point
calibration
Use a buffer solution in the range pH = 7.0 ± 0.5 for this pro-
cedure.
Note
Only the electrode asymmetry is determined in single-point
calibration. The slope of the last two-point calibration is
retained.
Note
Step 2 is not required if you use a temperature probe. The
TP message indicates an active temperature measurement.
