cable to the DRIVE (-) terminal of the analyzer. Short this test cable and the high voltage
output terminal together and confirm there is no high voltage output. Plug the red or white
high voltage test cable into the high voltage OUTPUT terminal. Connect the ground test cable
to the DUT first, and then connect the high voltage test cable to the DUT.
4.9.4 Test Procedure
4.9.4.1 GB/AC/DC/IR Test Procedure
1. Connect the DUT via correct connection.
When the title shows “MAIN MENU”, press the [TEST] Function Key to enter the TEST
function list; the title will display “TEST”. The display shows a list of STEPs which are set
and waiting for testing. The first field is STEP, the second field is test mode, the third field
is the test value, the fourth field is the output high limit value, and the fifth field is the test
result.
2. Press the [STOP] key.
Press the [START] key to start the test. When this key is pressed, high voltage will be
output and the DANGER LED will be illuminated.
The test is now running with the maximum current / voltage output
applied to the DUT. Use extreme caution when working near the
analyzer or the DUT.
The third field will show the output current / voltage reading, the fourth will show the
output resistance / current reading. The timer counts down or starts to count and shows
on status list.
3. PASS judgment
When all the tests have been completed and the fifth field test result shows PASS, then
the DUT is judged as GOOD and the output is stopped. The rear panel outputs the PASS
signal and the buzzer is turned ON.
4. FAIL judgment
If the measurement value is abnormal, the DUT is judged as FAIL and the output is
stopped. The rear panel outputs the FAIL signal and the buzzer is turned ON. The
analyzer stays on the function until the STOP key is pressed. The fifth field test result
shows FAIL.
