High-voltage Test Procedure

The following steps are performed while running the diagnostic tests. The check box for each of
the high-voltage tests below is assumed checked.
Caution must be taken when performing diagnostic tests on high-voltage systems. The
Series 90 high-voltage system generates up to 1500 vdc, and during testing applies 1500
vdc to the scanner board connectors. Keep hands clear of tester while tests are running.
Make setup changes only when a message window indicates to install or remove shorting
blocks or resistor banks.
1. Remove all interface cables from scanner
board connectors.
2. From the Calibration Group in the Home
Tab, click Capacitance Offset (1) button.
The Capacitance Offset dialog box, shown to
the right, will open
3. From the bottom of the Capacitance Offset
dialog box, click Calculate Offset button.
4. After capacitance offset is complete and
measurements are displayed, click Close
button.
5. From the Calibration Group in the Home
Tab, click Isolation Settling (3) button. A
Isolation Settling Calibration message box
will open as shown to the right.
6. Click the Calibrate Iso. Settling button.
7. After isolation settling is complete and
measurements are displayed, click OK
button. The isolation settling can take up to
10 minutes to complete.
8. From the Self Diagnostic Group in the Home
Tab, click the Diagnose System button.
9. . A message box opens prompting to remove shorting bars and resistor banks. Remove
all connections to the scanner boards.
10. Warning: Keep hands clear while this test is being run and click OK.
11. TestDiag performs several tests on various circuit components. Verify that Passed is
displayed after each of the following tests:
 System Status Test
 Shorts Test

Sense Line Test

Capacitance Test
High Voltage Warning
 Raw FET On Test

Raw FET Off Test
