Product Description

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
To acquire best accuracy, its decimal point can move according to different tested voltage(if <10V, two digits show after decimal point; if>10V, 1 digit shows after decimal point)
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
