5.7.2 Diagnostics

Chromeleon supports diagnostics functions for checking the performance of certain
module components. To perform the tests, the diagnostics toolkit (part no. 6040.3099) is
required. The kit includes all materials required for performing the tests.
Tip: The diagnostics functions in Chromeleon provide helpful information in case
of problems. The pump flow needs to be interrupted during diagnostics, and
thus it may take some runs afterward to reach the optimally stable operating
conditions again. Therefore, as long as the system operates properly, you
should not perform diagnostics between or shortly before running sample
series.
1. On the Control menu, select Diagnostics. The Control menu is visible only when a
control panel is open.
2. The Diagnostics dialog box lists all tests that are available for the devices in the
current timebase. Select a test. A wizard guides you through the test. For more
information about a test, see the Chromeleon Help.

Degasser vacuum in a SRD-3x00 Solvent Rack that
is operated from the pump.
Loading pump system (especially the fitting
connections) for leakage
Valves and seals for leakage. The test provides
information about the source for the leak.
Pressure pulsation and compressibility
compensation.
The permeability of the filter frit in the inline filter.
Only NC pump with Classic flow meter installed
The pressure transducer offset if you observe a shift
in peaks or if the gradients are not correct. Also
observe the information about the Pressure
Transducer Test on page 172.
Recommendation:
If you want to test the NC pump for tightness by
running the Detailed Leak Test, run the Pressure
Transducer Test first.
