3. Double sided strip light, LED light on indicates discharge is in progress, light off indicates discharge is complete 4. This capacitor discharge pen supports 2200UF capacitor discharge, which can quickly release the remaining power of high-voltage capacitors, but cannot be used for battery discharge 2. The discharge pen can automatically and intelligently recognize the discharge time without distinguishing electrodes, and the discharge is constant without 1. Capacitor discharge pen requires no polarity distinction; probes feature elasticity with flexible extension and retraction to prevent crushing. NOTE: The needle spacing is Non-adjustable. 5. Wide range of use: Suitable for the production, testing, and maintenance of electronic products, it can quickly release residual voltage of capacitors, protect operators from , and prevent product damage., Weight: 0.0110231131 Pounds, Manufacturer: Prterver
