■ Enter the conductivity of the standard used.
c(KCl) = 1 mmol/L can be used as a standard solution. This is
derived from the optionally available conductivity standard
6.2301.060 (KCl 0.1 mol/L) through dilution with distilled water. The
conductivity of this diluted solution is:

Alternatively, the conductivity standard 6.2324.000 (undiluted) can
be used.

Start determination and check the values
■ Click on [Start] to start the determination of the cell constant.
After the determination is finished, the dialog window Enter/Check
cell constants appears again.
If you wish to accept the displayed values, click [OK].
If you wish to maintain the old values, click [Cancel].
4.4.2 Determining Delta T
The temperature correction Delta T indicates the deviation of the cur-
rent temperature of the sample from the temperature in the heating block
and belongs to the method as a parameter (see Chapter 4.5.2, page
60). It can automatically be determined with the calibrated, external tem-
perature sensor (part of the optionally available GLP test set, see Optional
accessories, page 185).
