ICS-90 Pressure and Conductivity Diagnostics
Use this procedure to test the variance in pressure and conductivity readings for the Dionex ICS-90 Ion Chromatography System.
Verify that the ICS-90 pump is on.
Open the ICS-90 (or ICS-90A) System Wellness Control Panel (see 
Opening a Wellness Control Panel).
If you are unsure whether your system is an ICS-90 or ICS-90A, check the model data label on the rear panel.
Under Diagnostic, click the Start script button. The ICS-90 begins collecting pressure and conductivity readings. To stop the test, click the Stop script button. The ICS-90 reports the minimum, maximum, and variance results for both pressure and conductivity.
To test the conductivity variance on the electronics alone, select the Dummy Cell check box before running the test.
