GLP conductivity test
763 PVC THERMOMAT CONTROL / Tools / GLP test / Conductivity
This menu item is used to start the automatic GLP test for conductivity
measurement. This test can either be carried out with a standard solu-
tion with known conductivity or with the 6.2109.030 Test resistor which
is included in the 6.5616.000 GLP test set available from Metrohm as
an option. The test resistor must be connected to the electrode con-
nections 20 20 of the 763 PVC Thermomat.
In the GLP test a separate window opens which guides you through the
test step-by-step. The next step is reached with , the previous
step with and the test is aborted with .
The cell constants of the conductivity cells have to be determined
before carrying out the GLP conductivity test with standard solutions
for the first time (see section 4.4.1).
Proceed as follows to carry out the GLP conductivity test:
1 Select instrument
• Select unit 1...4 in the control window for which the GLP
conductivity test has to be carried out.
• If the GLP test is carried out with the test resistor carry on
from step 2, otherwise continue with step 3.
2 Carry out GLP test with test resistor
• Click on 763 PVC THERMOMAT CONTROL / Tools / GLP test /
Conductivity and click on in the GLP test window.
