100a Digital Display Voltmeter Ammeter Zfx Vc288 Dual Led Voltage Current Tester Monitor Panel Gauge With Shunt

This is 0.28-inch Digital Display Voltmeter Ammeter DC 100V 100A LED Amp Volt Meter With Shunt. This Amp Voltmeter will measure up to 100 VDC with a 0.1-volt resolution. Moreover 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 display 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.In addition  this 3 wire harness is used for a ground that connects directly to the battery or supply ground of the load.

Note: The meter with a range100A must be connected to the shunt to measure the current no matter whether the measured current is less than 10A! Otherwise, it will burn the header.
