24G wireless mission, Hall sensor measuring current, charge and discharge bidirectional current detectionWireless data mission avoids the interference caused by the complicated wiring between the display and the detection module, and the wiring is easier.The Hall sensor is used to realize non-contact current detection without disconnecting the wire, which is safe, reliable and convenient.Voltage, current, , temperature, capacity, percentage of remaining capacity, and running time are displayed simultaneously.It has the -off memory function, and the AH number before the -off can be memorized after the -off.the displays more comprehensive, clear and easy-to-observe data.Input voltage: when self-powered, measuring range: 6V-80VMeasuring range when external supply: 0-120VInput current measurement range: 0-100AExternal supply voltage: 6-60VDisplay mode: 24 inch color LCD displayVoltage: 001V-120VCurrent: 01A-100ACapacity: 0001AH-6500000AHEnergy: 0000KWH-9999KWHTime: 0-100 hours value: 999KWTemperature: 1-100Voltage: +/- 1%+2 wordsCurrent: +/- 1%+5 wordsTemperature: +/- 15Measurement rate: 5 times/secRelay delay time: (0-60) SCommunication distance: 10 meters for a single group in an open areaOVP (over voltage protection): 001V~500VLVP (undervoltage protection): 001-500VOCP (Charge Overcurrent Protection): 0-200ANCP (discharge overcurrent protection): 0-200Acolour: blackMaterial: PCBPackage Contents:1 x display module3 x 2P red and black wire1 x male to male USB20 cable1 x measurement module (including a measurement board and a Hall sensor)Only the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
