1.The product is compact, easy to use, and can be operated with one hand 2.The probe has elasticity, flexible extension and contraction, and is not easily crushed. The needle spacing can be adjusted 3.The discharge pen uses a 1000v mos tube, and the discharge voltage should not exceed 1000v 4.The discharge pen adopts dual led to indicate the discharge process. The red led lights up when the high voltage is high, and the green led lights up when the low voltage is low. The turning voltage is about 42v 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 electric shock, and prevent product damage Please note: the physical slightly color difference or difference, does not affect the use, please do not mind, thank you! Matters needing attention:After the green led goes out, it indicates that the discharge is complete, and there is still a residual voltage of about 6v in the capacitor at this time Do not touch the circuit and exposed metal during discharge Do not discharge for a long time, please pay attention to heat dissipation during discharge There is no limit to the discharge capacitor, the larger the capacity, the longer the discharge time Color: As shown Material: plastic Package Contents: 1 x Capacitive discharge pen Only the above package content, other products are not included. 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.
