This capacitor discharge pen supports capacitor discharge below 1000V, which can quickly release the remaining power of high-voltage capacitor and cannot discharge the battery. Features: Pen type design and portable size, it is convenient for you to carry and for your daily use. This capacitor discharge pen supports capacitor discharge below 1000V, which can quickly release the remaining power of high-voltage capacitor, but cannot for discharge the battery. It can quickly release the residual power of capacitors generated during production, testing and maintenance of various electronic products (such as switching power supplies, digital cameras, mobilephones, TV power supplies, etc.) to protects operators from electric shock and products from damage. The discharge pen can automatically and intelligently identify when discharging, without distinguishing positive and negative electrodes, constant discharge, no sparking. With the LED indicator light, when the indicator light is on, it indicates that the discharge is in progress, and when the indicator light is off it means the voltage is about 9V and the discharge is finished. Specifications: Material: plastics Apply for: Capacitor1000V Discharge method: constant current discharge Discharge to: below 2V Package size: 160 * 25 * 25mm / 6.3 * 1.0 * 1.0in Package weight: 30g / 1.1ounce Packing List: 1 * Capacitor Discharge Pen 1 * Storage Box
