￭ 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 conductiv-
ity 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:

The conductivity is measured sequentially at all channels.
After the last measurement is completed, the dialog window with
the test results appears.
