Frequently Asked Questions
Q: What is the voltage and current measurement range of this mini digital voltmeter ammeter?
A: This dual LED display meter measures DC voltage from 0 to 100V and DC current from 0.000 to 9.999A (approximately 10A). It requires a separate working supply voltage of DC 4V–30V to power the display itself.
Q: How do I wire this 5-wire voltmeter ammeter to my circuit?
A: The 5-wire configuration includes two wires for the power supply (to drive the display), two wires connected across the voltage measurement points, and one wire for current sensing (in series with the load). A wiring diagram is typically printed on the module itself or included with the product. Always ensure your circuit is de-energized before connecting.
Q: Can I use this voltmeter ammeter for solar panel or battery monitoring?
A: Yes! This mini panel meter is widely used in solar charging systems, battery bank monitors, DIY power supplies, and any DC application where simultaneous voltage and current readings up to 100V / 10A are needed.
Q: What panel cutout size do I need to mount this meter?
A: The module body measures 48 × 28 mm (1.89 × 1.1 in). You should prepare a panel cutout slightly smaller than the bezel dimensions to allow a snug fit. Check your specific mounting enclosure dimensions before installation.
