| Phenomenon | Reason | Solution | |
| 1 | Green light don't turn on when power switch connected | Current lines open a circuitPower fuse fusing | Change power lines Change power fuse |
| 2 | Red light don't turn on when push the red button | Pressure regulating potentiometer didn't return to 0 | Potentiometer return to 0 |
| 3 | Red light turns on when push the red button, while raise voltage, red light turns off, red light turns on | High voltage output terminal tester has short circuit | Check the output electric cable.Check the tested products |
| 4 | During raise voltage, red light turns off, green light turns on. | Tester discharge or break-down over voltage or over current protection movement | Check the tested products reset setting valu |
