Dialog window: Method ▶ CAL LOOP Opt ▶ Properties… ▶ CAL LOOP Opt - 'Com-
mand name'
Loop command for the calibration of colorimetric sensors, used
together with the CAL MEAS Opt command.
The concentrations which are to be measured with the CAL MEAS Opt
command are defined in this loop command. Each time the loop is exe-
cuted, the validity of the concentration measurement is checked, and at
the end the calibration data for the colorimetric sensor is calculated.
Appearance
The command has the following appearance:
Parameters
The parameters for the CAL LOOP Opt command are set in the following
