7. Voltage breakdown (BREAK)
If the leakage current of the object under test during the AC / DC withstand voltage test is far
beyond the range that the instrument can measure, and the arc current is far beyond the normal
value that the instrument can measure, it will be judged by the program as resistant. The test
failed due to a crash, and the LCD will display:

8. Overcurrent failure (OVER)
If the output current of the DUT during the AC / DC withstand voltage test exceeds the normal
output range of the instrument, it will be determined by the program as a test failure caused by
overcurrent, and the display will show:
