Operation
105
Note
This method of automatically determining the cell constant
by calibrating in the 0.01 mol/l KCL control standard can
only be used for measuring cells with a cell constant in the
range 0.450 ... 0.500 cm
-1
or 0.800 ... 1.200 cm
-1
.
Calibration
evaluation
After calibrating, the instrument automatically evaluates the
current condition of the calibration.
The evaluation appears on the display.
Calibration protocol The calibration protocol contains the calibration data of the
current calibration.
Note
You can automatically print out a calibration protocol after
the calibration. To do so, connect a printer to the interface
according to section 4.5.3 before calibrating. After a valid
calibration, the protocol is printed.
