2.7.10.1 Available Sets of Calibration Standards

pH ARC Sensors can store and operate six different sets of calibration standards each having max 12 calibration standards. Before calibration the operator has to select one defined set to operate with. Default setting is the HAMILTON set of calibration standards.

The operator can change the selection of sets at any time, without compromising prior calibration data at CP1 / CP2.

In register 9472 the available sets of calibration standards are defined.
