Manual Calibration Procedure - pH
Requires prepared buffers. System calibration is possible with two known pH
solutions within 0 to 14 pH (buffers of pH 4.01, 7, or 10 are recommended,
but use a buffer close to your own process value.)
Single-point calibration sets
STANDARD only; Signet
recommends a two-point
calibration to set SLOPE in
addition to STANDARD.
