Frequently Asked Questions
Q: Does this digital voltmeter ammeter work with AC power?
A: No — this panel meter is designed for DC circuits only. It measures DC voltage from 0–100V and DC current from 0–10A. It is not compatible with AC power sources.
Q: Does the meter need its own power supply?
A: Yes, an external DC power supply of 4–30V is required to power the meter's display. If the meter supply shares the same circuit as the load being measured, ensure the circuit voltage stays within the 4–30V range to avoid damage.
Q: What is the panel cutout size needed to install this voltmeter ammeter?
A: The required panel cutout is 46mm × 27mm. The meter's overall body dimensions are 48mm × 29mm × 21mm, making it a compact and easy-to-install solution for most DIY enclosures and project boxes.
Q: How accurate is this dual display panel meter?
A: The voltage reading has a tolerance of ±1% and the current reading has a tolerance of ±0.1%, with an auto-ranging resolution of 0.01V and 0.01A. The display refreshes every 300ms for near real-time monitoring.
