What should I notice?
1.The power supply range of this meter is 4~30V (it will be broken if it exceeds the range), and the measurement range is 0~100V.
2.Make sure the thick black wire is connected to the negative side of the battery and the thick red wire is connected to the negative side of the load.
3.If it is directly powered or the independent power supply is grounded with the equipment power supply, just disconnect the thin black wire.
4.All rectified alternating current must be filtered by an electrolytic capacitor of more than 1000uF before powering the meter.
