0 39 LED Voltage Current Display DC 4 5 100V Multimeter Panel Digital Voltmeter Ammeter 0 50A Amp Volt Meter LED Voltage Amperage Monitor Gauge with 50A 75mV Shunt for Automotive Motor Battery

Feature : Voltage Measuring Range : DC 4.5-100V Voltage Resolution : 0.01V under 10V 0.1V between 10V and 100V Current Measuring Range : 0.0-50.0A (If the current is higher than 20A, a shunt is required, or the meter will burn) Current Resolution : 0.1A Display : 0.39"" LED display Measuring Rate : ?500mS/time Shunt : 50A/75mV Extreme Working Condition : Working Temperature : -10??+65? Working Humidity : 10?80% ( No Condensation) Working Air Pressure : 80?106kPa Connecting Method : COM: Common terminal of power supply negative pole V+ : Positive pole of tested voltage, positive pole input terminal of power supply A+ : Positive pole input terminal of tested current ( This meter adopts common-ground design that earth wire of measuring terminal is interlinked with earth wire of power supply, so A+ can only be connected between the tested device negative pole and power supply negative pole. The meter will burn if connected wrong.) Note : If the meter is used as voltmeter, it is suggested that the yellow wire and black wire are connected together. Package included : 1 X 0.39 inch digital voltmeter ammeter 1 X 50A/75mV shunt
