Dual display voltage detector ammeter panel ampere voltmeter DC 0-100V 10A 50A 100A digital voltmeter ammeter

Measuring range: 0.0V-100V Test range: 0-10A 0-50A 0-100A Power supply range: DC4-30.0V Voltage error: ± 0.1% Current error: soil 1% External splitter specifications: 75 mOhm Working current: Refresh rate: about 300mS once Display mode: double three-digit 0.28" LED digital tube Display color: red + red, red + blue optional Lead length: 15cm Appearance size: 48X29X16mm Mounting hole: 46X27mm Working temperature: -10℃-65℃

Precautions: 1. The power supply voltage of the meter must be 4-30V, and independent power supply is required if it exceeds 30V. Please connect according to the figure. The four points of the shunt cannot be changed at will! 2. The digital display meter and the shunt are used together. 1A, 10A can not be used with 50A, 100A shunt, please know! 3. No matter whether the measured current is less than 10A, the meter with a range of 50A or 100A must be connected to a shunt to measure the current! Otherwise it will burn the meter head.
