Two-wires connection: simply connect the red and black wire to positive and negative pole respectively.
With reversed connection protection, meaning meter will not burn when connected reversely.
0.36" LED digits visible display; it requires low voltage to start; if volt is less than 3.5V, the LED will dim but not affect measurement.
It can test voltage of 18650 or lithium battery, NiMH battery pack, moto, auto, car, etc; screw potentiometer in back side for more accurate results.
