NOTE
Measured value recording
Depending on the settings of the measured value criterion, the
recording of the measured value may take some time. During the
measurement, hold the sensor steady and do not touch the sam-
ple vessel with it.
For measurements that take longer, we recommend using a stand
to secure the sensor in place.
Finishing measurements
After the last measurement, rinse the sensor and follow the stor-
age instructions for the sensor.
4.9 Conductivity measurement
This chapter describes the required steps to carry out a simple conductivity
measurement with calibration. The description is limited to only the indis-
pensable steps and will enable you to carry out first measurements with
the instrument directly.
4.9.1 Determination of the cell constant (calibration)
NOTE
Measuring channel selection
In order to perform the calibration, you have to select the correspond-
ing measuring channel in the main dialog.
You cannot perform a calibration in the two-channel view in the main
dialog.
Determination of the cell constant
The calibration parameters are set to default values (see Chapter 4.7.2,
page 39).
If the Report selection dialog is set to on in the Calibration param.
menu dialog, then the calibration data will be output immediately.
