The Dual Digital Voltmeter Ammeter is a compact DC panel meter designed for real-time monitoring of voltage and current in electronic systems. It features a dual-color LED display that simultaneously shows voltage and current readings, allowing quick system status verification. With support for voltage measurements up to 100V and current measurements up to 10A through a built-in shunt, it provides accurate and reliable monitoring without requiring external current sensing components. Its compact panel-mount design makes it suitable for power supplies, battery systems, solar projects, and electronic test equipment.
Notice
The voltage between the thin red and thin black lines must be within DC 4.5-30V
The ammeter can only be connected to the negative of the device under test
10A below ammeter (include 10A), built-in shunt, does not require external shunt
When the black thin line vacant, it is better to use insulating tape around the exposed part of the wire, to prevent short circuits
If just be used as a voltmeter, it is recommended that the yellow line and the black line were connected together, to prevent the ammeter digital flashing
