DC 4.5-30V 0-50A Dual LED Digital Volt Meter Ammeter AMP Power

Product Features:
1.The small size of the two-color dual instrument.Voltage and current can be displayed on the same screen at the same time
2.This instrument test voltage, current, power supply is taken from the test loop.No additional power supply
3.The the instrument test voltage supply range: DC4.5 ~ 30V,The reverse does not burn,
Note: The maximum input voltage can not exceed 30V, otherwise there is the danger of burned
4.The instrument is equipped with five wiring.Convenient access to car / battery car / motorcycle car line,,Used to monitor the battery voltage,,Grasp the battery voltage state,can also be used for other products, the use of Voltage/current measurement.

Wiring Method:
The instrument with five lines:
Thin black line: Header supply ground
The Thin Red Line: Header powered regular (Note, thin red and black line between the voltage can not exceed 30V)
Thick black lines: public test end
Thick red line: measuring the positive voltage input terminal
Yellow lines: current input terminal; header uses of design, the measuring end of the ground and the ground of the power supply side is the same, it is only then measured the back of the device, as shown in the following figure, the wrong will burn (such as single voltmeter, it is recommended that the yellow line with black lines together, to prevent outside interference cause ammeter digital flashing)
