Digital voltmeter ammeter measure voltage DC 4.5V-100V; Operating current 0-50A. Dual meter panel display is 0.39'' crisp and bright LED screen displays voltage & current value. Multimeter panel with voltage & current equipped with calibration potentiometer, if there have any error, you can calibrated by yourself. DC current meter voltmeter wide application for monitoring storage battery, solar panel, model railroad, RV, motorcycle, house batteries, motor, etc. NOTE --- the shunt should be connected when wiring, otherwise the meter will be burnt. 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
