Frequently Asked Questions
Q: What does this digital voltmeter ammeter measure?
A: This dual display panel meter simultaneously measures DC voltage in the range of 0–100V and DC current up to 10A. It auto-ranges with a resolution of 0.01V and 0.01A, making it accurate and easy to read for a wide variety of DC electrical projects.
Q: Does this meter require an external power supply?
A: Yes — the meter requires an external DC supply voltage of 4–30V to power its display. It is designed for DC circuits only and is not compatible with AC power. It draws less than 20mA, so it adds minimal load to your system.
Q: Is there protection against incorrect wiring?
A: Yes. This voltmeter ammeter includes built-in reversed connection protection, which helps safeguard the unit if the leads are accidentally connected with reversed polarity, giving you added confidence during installation and testing.
Q: What are common applications for this panel meter?
A: This meter is widely used in solar power monitoring, battery management systems, DIY bench power supplies, automotive electrical testing, and electronics prototyping. Its compact 48 × 29 × 21 mm size makes it ideal for panel-mount installations in project enclosures.
