  • Page 41: Ph Calibration

    7.4 pH Calibration The instrument provides multi-point standard buffer solution calibration. You may decide how many points to calibrate the measurement system(up to 3-point). The principle is according to “Method of Least Squares”. Apply linear regression to calibration the electrode’s slope and zero point (Asy, Offset or Zero point). When calibrating a electrode, you may calibrate 1 to 3 point by any sequence to provide linear regression for mV and pH multi-calibration of a electrode, and to show the electrode’s slope and zero point(Asy, offset or Zero point) at 25°C.
