5.6.7 Calibration

commands

Commands for calibration of pH- and ion selective sensors.

General

The commands

CAL LOOP

and

CAL MEAS

are available for calibrating electrodes.

The number and type of buffers or standards respectively is defined in the loop
command

CAL LOOP

whereas the measurement is done with the command

CAL

MEAS

. The validity of the measurement is checked after each pass of the loop. The

calibration data for the electrode are determined at the end.

The basic structure of a calibration method looks as follows:
