Parameters: Power supply: DC 3.8-30V Power consumption: Refresh rate: about 3 times/s Voltage range: 100V Voltage internal resistance: 400K Current range: 100a Current internal resistance: 75mV Shunt Test accuracy: 0.2 percent + 2 words Current resolution: when within 100a, 00.00-99.00; when 100a, 100.0. Overload capacity: 120a, one minute (when within the overload capacity, the display still can show but please don't over the specified time. We suggest the average current be about half of the range) Display color: red voltage + Blue current Hole size: 45.5mm 26mm Dimensions: 48mm 29mm 20mm with reverse polarity protection, but the input still can't over 30V when connecting reversely. The meter can measure positive voltage and positive/negative current, the Decimal point will Flash when measuring negative current, and it will automatically move when less than 1a, unit is MA. current sampling uses an independent AD conversion chip, more stable and accurate. Very suitable for monitoring battery. note: the meter must be powered by an isolated and not common ground power supply, or it will cause large errors when measuring current, and the best is DC 5V. You can also make an isolated power supply by an isolated module. the meter should be connected to the negative to measure current, or it will be burnt. package includes: 1 x Volt and amp meter 1 x 100a/75mV shuntProduct Features
