Package Includes:
1x Digital Panel Voltmeter
- 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, one 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.
