How should insulation and voltage withstand testers be used correctly?

The quality of products is now an issue that every manufacturer cannot ignore. Assuming that the work is not done well, it will affect the company's reputation and lead to customer distrust. Therefore, regulatory requirements have become one of the important technical specifications. The various elements of the quality application of insulation and withstand voltage testers are very important.

Nowadays, the application scale of withstand voltage testers is becoming more and more common, and the frequency of use is gradually improving. However, it is also difficult to avoid some things that cannot be used. There is advance preparation for everything, and of course, there is no exception regarding this device. Some components, as well as the grasp of mission principles, especially the application after power on, need to be careful and applied carefully.

When powered on, the withstand voltage tester must be connected to the ground to avoid leakage, and the short circuit piece for testing leakage should also be connected in advance and measured in advance. Also, it is important to prepare the reflection instrument in advance when starting up and cultivate a habit of reflection before use. Set the voltage to low before starting up. Based on the requirements of mission testing, choose the correct mission approach. And the voltage is between zero to 25000 volts or 0.5 volts.

When using it correctly, the first thing to do is to set the voltage to zero, so that the entire instrument is reset, and then connect the low end of the instrument to be tested to the common end of the device. The instrument should not touch the air, but the device should touch the ground. End initiating the device and change the voltage scheduling button in a clockwise direction so that the input voltage reaches a certain set position.

Assuming that a qualified light flashes, it indicates that the instrument is qualified. Otherwise, an alarm will sound and it will be considered unqualified. After pressing the reset button and eliminating the alarm, the voltage regulator should be lowered and the power supply should be properly closed.
