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+ only can be connected between the tested device negative pole and power supply negative pole.
the meter will be burnt if connected wrong.)
Note: If the meter is just used as voltmeter, it is suggested that the yellow wire and black wire are connected together.

Package Included:
1 x DC meter
1 x 50A Shunt EFFORTLESS WIRING & COMPACT DESIGN: DROK tester multimeter provided with 3 wiring terminal, when testing voltage and current, the power comes from the return circuit, so you don't need extra power supply. Besides, this meter can display voltage and current simultaneously in such a tiny size (70mm * 40mm * 30mm).
WIDE MEASURING RANGE: The multiple meter has wide measuring range (Voltage measuring range: DC 4.5-100V; Current measuring range: 0-50A). What's more, this ampere voltage gauge has voltage calibration potentiometer and current calibration potentiometer, if there is an error, you can adjust them by yourself.
COMMON-GROUND DESIGN: DROK volt amp meter digital is provided with 3 wiring terminal, when testing voltage and current, the power comes from the return circuit, so you don't need extra power supply.
STRONG INTERFERENCE CAPABILITY: The current voltage monitor has strong anti-interference capability, it can quickly display refresh rate; with exquisite SMT technology, it has good consistency. And this ammeter voltmeter panel owns shell, safe, reliable and dustproof.
WIDE APPLICATION: DROK dc voltmeter ammeter has handy connection and wide application, for example, it can be applied to monitoring storage battery, DC adjustable power supply, or voltage and current changing state of other device.
