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.<br> During the normal discharge process, the green status indicator light will be on. If the indicator light goes out, it indicates that the energy of the energy storage capacitor has been discharged below the safe energy. It is a practical tool for power supply maintenance and safe discharge of high-voltage energy storage capacitors.<br> The pen tip can be removed, if thewire is broken in use, it is easy to<br> 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.<br> Colour:Black & Red<br> Material:plastic<br> Package Contents:<br> 1 x Capacitor Discharge Pen<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
