Checking Test Start and Test Results
7.2 Checking Test Start and Test Results
Press the instrument START button to implement the test. (You can start the test from either
communications or external control terminal as well.)
When a test finishes, the test results are output to the screen, communications, and external control
terminal (EXT. I/O).
IMPORTANT
If any of the judgment results are FAIL, it views that dielectric breakdown as having started and the test
ends at that point in time.
If the judgment results are all PASS, implement testing until max. voltage is reached.
