Diagnostics (UltiMate 3000 Series)
Degasser Vacuum Test

Run this test to check the degasser's vacuum. If you want to run the test for an external degasser of the UltiMate 3000 system (SRD-3x00 degasser), verify that the degasser is electrically connected to the pump and that the Power LED on the degasser's front panel is blue.

How to

  1. On the first test page, click Next> to proceed with the settings required for the test.

     Tip: 

    If the Next> button is not active on the first test page, the pump is not connected in Chromeleon or is in Standby mode. Connect the pump to Chromeleon before you continue by selecting the Connected check box. If the pump is in Standby mode, also clear the Standby check box.

  2. Optional: Enter a descriptive text in the Comments field, e.g., the reason why the test was performed.

  3. Prepare the pump. (Grayed test steps can be ignored.) After each completed step, click the Done button.

    1. External degasser only: Enter the degasser's serial number. To test a Dionex SRD-3x00 degasser, the last four digits of the degasser's serial number must be 0701 or higher, or the first digit is 8 or 9. (The serial number is provided on the degasser's type label.)

    2. Reduce the flow rate to 0 ml/min by clicking Execute. This will automatically set the flow to the required value.

    3. Purge the pump if required. Click Purge and select the required settings in the Pump Purge dialog box. Click Yes if you have already purged the pump.

  4. Clicking Next> takes you to the next test step(s). Follow the instructions on the test panels. The last wizard page shows the test result.

  5. When the test is complete, click Finish and Preview Report to view or print the report with details of the analysis. Click Finish> to quit the test panel without viewing the report. For information about troubleshooting, click Open Troubleshooting Guide.
