Small and , easy to carry.Rapid discharge without Discharge does not distinguish between positive and negative poles The 4-digit 8888 digital tube displays the remaining voltage and can be used as a voltmeter. Suitable for discharge below 800V.Discharge voltage range Less than 800VDC How to convert AC voltage to :The voltmeter shows . If it is AC voltage, it should be converted to by simple calculation.AC voltage = voltage displayed on the voltmeter/0.9 (conversion factor is 0.9). Le. g: If the voltage on the voltmeter is 207VDC, the actual AC voltage is 207VDC/0.9=230VAC LED color: blue Max. Discharge energy (): 150J Input port: 4mm banana socket. Probe cover material: antifreeze PVC. Uses: switching power supplies, digital cameras, TV power boards, high-voltage large electrolytic capacitors, etc. Function: Discharges capacitors and protects products and operators from . User Guide: Insert the red and black probe tips into the 4mm banana socket. The red and black probe tips contact the two pins of the capacitor without distinguishing between positive and negative poles. The voltmeter will show the remaining voltage of the capacitor. ----When the voltage is around 10V, the LED display will turn on and off. At this time, the probe should continue to discharge for about 10 seconds, and then it can be discharged below 5V. Notice: 1. If used as a voltmeter, when measuring AC voltage 230V, the measurement time should not exceed 20s. 2. To the safe use of the discharge device, it is recommended to use it in situations below 600VDC. 3. Before discharging, please disconnect the 230V AC voltage. 4. Below 10V, the voltmeter does not display, but it can continue to discharge. 5. The energyon the capacitor should not exceed a maximum of 150J.
