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:
The calibration can be carried out by manual changing of buffers/standards or by
automatic changing in combination with a Sample Processor.
Commands
The following commands can be selected for calibration:
•
CAL LOOP pH
Calibration loop for calibrating pH electrodes.
• CAL MEAS pH
Measuring command for calibrating pH electrodes.
• CAL LOOP Conc
Calibration loop for calibrating ion selective electrodes (ISE electrodes).
•
CAL MEAS Conc
Measuring command for calibrating ion selective electrodes (ISE elec-
trodes).
