The pen tip can be removed, if thewire is broken in use, it is easy to During the normal discharge process, the green status indicator light be on. If the indicator light out, it indicates that the of the storage capacitor has been discharged below the safe . It is a practical tool for power supply maintenance and safe discharge of high-voltage storage capacitors. The high-voltage capacitor discharge pen adopts a constant current discharge design and can be used for both AC and DC without distinguishing the positive and negative poles. The gold-plated extra-tip test pen is connected and can flexibly respond to the needs of various occasions. The circuit design is reasonable, regardless of the positive and negative poles, the positive and negative polescanbe connectedfreely.Just to the two poles of the capacitor., Weight: 0.15652820602 Pounds, Manufacturer: Kueohse
