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 appearanceDescription:M520 is a voltage, current and power measuring instrument. It can only measure and display the voltage, current and power of the circuit under test. The displayed value can be fine-tuned through an adjustable resistance. The actual voltage and current of the loop has no effect.Do not work with above 20V during use, otherwise it will easily cause overvoltage damage to the product.The 10A range product comes with a shunt resistor, and there will be a short circuit at the test end of the direct current measurement. As long as the meter is connected in series with the load according to the wiring diagram, it can be used normally.This only has a 10A range, no 50A and 100A ranges.Specifications:Operating VoltageThe working voltage of the instrument is DC 5~30V, and 5~12V is recommended.The thin red wire is the positive pole of the working power supply, and the thin black wire is the negative pole of the working power supply, which belongs to the common ground with the thick black wire; the limit voltage connected to the thin red and black wire cannot exceed 24V, and 12V power supply is recommended.Measuring rangeThe voltage measurement range is 0~100V, the display mode below 10V is 0.0V, the voltage starts at 0.1V, the error range is ±1V, the current measurement range is 0~10A, the current starts at 0.03A, and the error starts at ±3%Shunt resistorOn-board shunt resistor, no need for external shunt, just use it directly according to the wiring diagramThe shunt resistance is connected in parallel with the current test line, and the no-load test will cause a short circuit alarm. When using, connect the thick red line to the negative
