0.28" LED Voltmeter Ammeter, DC 100V 10A Amp Voltage Current Volt Amp Meter Tester, Red and Blue Dual Digital Panel

Features: - If the current shows 0, please check the wiring carefully. - Inaccurate current display: If the direct or independent power supply shares the same ground with the equipment power supply, just disconnect the thin black wire. - All AC rectified electricity must be connected to an electrolytic capacitor above 1000uF for filtering before supplying power to the meter. - When discharging: Battery, switching power supply and transformer are power supply, and resistance, electric lamp, motor and electric equipment are loads. - When charging: Charger, generator and solar energy are the power supply, while charging pool and battery are the load. Specification: Working Voltage of Meter Itself: DC 4V - 30V Working Current of Meter Itself: Less Than or Equal to 20mA Voltage Measuring Range: DC 0V - 100V Current Measuring Range: DC 0A - 10A Voltage Resolution (V): 0.1V Current Resolution (A): 0.01A Measure Accuracy: 1 Percent (-1 Percent to 1 Percent) Display: 0.28 Inch Digital Tube(Two Color Blue and Red) Refresh Rate: About 300mS / Times Operation Temperature: -10 Degree Centigrade to +65 Degree Centigrade Note: - The maximum input voltage can not exceed 30V. Otherwise the meter will be burned. - The wiring for discharging is different from that for charging. - The current can only be measured in series at the negative pole of the power supply and the negative pole of the load. - Make sure that the thick black wire is connected to the negative of the battery and the thick red wire is connected to the negative of the load. Package Include: 1 x DC 100V 10A Voltmeter & Ammeter 1 x Red Black Line 1 x Red Black Yellow Line 1 x Shunt
