Click on the menu item Tools

GLP test Conductivity... and

confirm with [Next >].
The following dialog window appears:

Select the option Use standard solution.

Under Conductivity of standard solution, enter the conductivity
in µS/cm and confirm with [Next >].

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:
