4.8.4.2 Conductivity
The GLP test for conductivity measurement can be carried out either
with a standard solution with a known conductivity or with the test
resistor 6.2109.030. The test resistor is part of the optionally avaiable GLP
test set (see Optional accessories, page 180). The test resistor must be
connected during measurement at the electrode connector (3-
2 ) of the 873
Biodiesel Rancimat.
Carrying out the GLP test for the conductivity measurement
Proceed as follows to carry out the GLP test:
Note
Before carrying out the GLP test with standard solution for the first
time, the cell constants of the conductivity measuring cells must be deter-
mined (see Chapter 4.4.1, page 48).
1 Select instrument
￭ In the Control window, use the menu item View ▶ Unit x to
select the instrument for which the GLP test is to be carried out.
￭ Carrying out the GLP test with the test resistor: continue with
step 2.
Carrying out the GLP test with the standard solution: continue
with step 3.
