Usage Tips:Small and light, easy to carry. Fast discharge without is suitable for DC voltage discharge below 800V.Discharge does not distinguish between positive and negative poles. The 4-digit 8888 digital tube displays the residual voltage and can be used as a voltmeter.Uses: switching power supplies, digital cameras, TV power boards, high-voltage large electrolytic capacitors, etc.Function: discharge capacitors to protect products and operators from .Discharge voltage range Less than 800VDCLED color: blueMax. Discharge energy (): 150JInput port: 4mm banana socket.Probe cover material: antifreeze PVC.User Guide:Insert the red and black probe tips into the 4mm banana socket.The red and black probe tips touch the two pins of the capacitor, without distinguishing between positive and negative poles.The voltmeter display the remaining voltage of the capacitor. When the voltage is around 10V, the LED display turns on and off. At this time, the probe should continue to discharge for about 10 seconds, and then it can be discharged below 5V.How to convert AC voltage to DC voltage:The voltmeter displays DC voltage. If it is AC voltage, it should be converted to DC voltage 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=230VACColour:As ShownMaterial:ABSPackage Contents:1x Capacitor discharge meter Kit
