One thing to note is, this meter has 2 wiring harnesses. One harness is to provide power for the meters, that’s the 2 poles with a RED and a BLACK lead. Small size, portable, the magnitudes of voltage and current are displayed on the same screen at the same time.
This can be supplied anywhere from 6 volts DC up to 30 VDC. This is a separate power supply that is isolated from the source, it is possible to use the same supply but it seems to affect the amp meter reading. The 3 wire harness is used for a ground that connects directly to the battery or supply ground of the load.
There are different wiring variants with the same working functionality is available which will be shipped randomly.
If the input voltage is more than 5V then please use the buck converter.
