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.
