5PCS Digital Voltmeter DC5-30V 10A Voltmeter Ammeter Blue + Red LED Amp Dual Digital Volt Meter Gauge Electromobile Motorcycle Car

AmmetersDigital Voltmeter DC5-30V 10A Voltmeter Ammeter Blue + Red LED Amp Dual Digital Volt Meter Gauge Electromobile Motorcycle CarFeatures:1:2: There are voltage and current power display3: stable performance4: Simple to use5: Small appearance:M520 is a voltage, current and power measuring instrument. It can only measure and display voltage, current and power of circuit under test. displayed value can be fine-tuned through an adjustable resistance. actual voltage and current of loop has no effect.Do not work with above 20V during use, otherwise it will easily cause overvoltage damage to product. 10A range product comes with a shunt resistor, and there will be a short circuit at test end of direct current measurement. As long as meter is connected in series with load according to wiring diagram, it can be used normally.This only has a 10A range, no 50A and 100A ranges.Specifications:Operating Voltage working voltage of instrument is DC 5~30V, and 5~12V is recommended. thin red wire is positive pole of working power supply, and thin black wire is negative pole of working power supply, which belongs to common ground with thick black wire; limit voltage connected to thin red and black wire cannot exceed 24V, and 12V power supply is recommended.Measuring range voltage measurement range is 0~100V, display mode below 10V is 0.0V, voltage starts at 0.1V, error range is ±1V, current measurement range is 0~10A, current starts at 0.03A, and error starts at ±3%Shunt resistorOn-board shunt resistor, no need for external shunt, just use it directly according to wiring diagram shunt resistance is connected in parallel with current test line, and no-load test will cause a short circuit alarm. When using, connect thick red line to negative pole of load according to wiring diagram for normal use.Standard leadXH-2.54-3P red, black and yellow wire (total length of thin wire: 155mm)Thin red wire: positive pole of working power supply, can not be connected to a power supply above 30VThin black wire: negative pole of working power supply, and thick black wire on construction site, do not need to be connected when sharing power supplyThin yellow line: voltage test line, connected to positive pole of test circuit power supplyVH-3.96-2P red and black wire (thick wire total length: 165mm) current test wireThick red wire: positive pole of current test, which is connected to negative pole of load.Thick black wire: current test negative pole, connect to power supply negative pole, connect first and then break when disconnectedVoltage display fine-tuningIt is a display fine adjustment, not a major adjustment, adjustment is display voltage, but actual voltage cannot be adjusted!See round adjustable resistor of V-ADJ, find a flat-blade screwdriver and twist it!No-load current does not return to zeroNeither does this feature!Display powerReal-time power will alternate with current (about 10 seconds alternate)
