Everyone is familiar with the use of lightning surge tester, but I don’t need to talk about the use of lightning surge tester. What should we pay attention to in the process of using lightning surge tester? I also want to know something that many people don’t know. Today, I’ll tell you what we should pay attention to in the process of using lightning surge tester

Precautions for lightning surge tester

1. The tester must be trained and qualified before operating the equipment. When the hand is wet or the relative humidity exceeds 75%, do not use the equipment, because there is a high-voltage pulse added to the output terminal block (such as 2W, 500W, L1, L2, L3 and other ports). If the wiring is changed, it is necessary to confirm that the high-voltage power supply is disconnected;

2. The f.g. terminal of the lightning surge tester should be well grounded. This equipment uses the high-voltage mercury switch to generate high-voltage pulse. It is strictly forbidden to carry out the test under the inclined state of the equipment, with high voltage inside. Do not disassemble or open the shell at will;

3. In case of emergency, press the emergency key, the instrument will quickly stop the surge output, turn off the internal high voltage, and quickly cut off the power supply. In order to ensure the comparability and repeatability of the test, the test configuration must be standardized;

4. Non relevant personnel are strictly forbidden to operate this instrument
