Frequently Asked Questions
Q: What does this digital voltmeter ammeter measure?
A: This AC digital LCD voltmeter ammeter measures both AC voltage (50V–500V) and current (10A, 50A, or 100A) simultaneously on a dual LCD display. It uses a high-precision built-in current transformer for accurate, real-time readings of your AC circuit.
Q: How do I install this panel-mount voltmeter ammeter?
A: Installation is straightforward — the meter is designed for standard panel-cut mounting. Simply cut the appropriate-sized hole in your enclosure or switchboard panel, slide the meter in, secure it with the provided clips or bracket, and connect the voltage leads and current transformer wires to your AC circuit. Always ensure the power is isolated before installation.
Q: Can I use this voltmeter ammeter for a 220V household circuit?
A: Yes. The meter supports AC voltages from 50V to 500V, which covers standard 110V and 220V household supplies as well as higher-voltage industrial applications. Select the appropriate current range (10A, 50A, or 100A) based on your circuit's expected load.
Q: What are the physical dimensions of this meter?
A: The meter has a compact footprint of 48mm × 29mm × 22mm, making it easy to integrate into control panels, generator housings, solar charge setups, or custom enclosures without taking up significant space.
