What is the measurement range of this digital voltmeter, and does it work on both single-phase and 3-phase systems?

This voltmeter measures AC voltage from 30V to 500V, making it compatible with standard single-phase supplies (110V/230V) as well as 3-phase industrial systems up to 500VAC. It measures line-to-neutral or line-to-line voltage depending on how you wire it into your panel.

How do I use the built-in potentiometer to calibrate the voltmeter?

Connect the voltmeter to a known, stable reference voltage source, then use a small flathead screwdriver to gently adjust the onboard potentiometer until the display matches the reference reading. This allows you to compensate for any minor variance and ensure accurate readings specific to your installation.

What are the panel cutout dimensions required to mount this voltmeter?

This voltmeter is designed for standard 22mm × 22mm square panel cutout mounting, which is common in most DIN-rail enclosures and electrical distribution boards. Please verify the exact cutout dimensions against the physical unit before installation, as minor manufacturing tolerances may apply.

Does this voltmeter require a separate power supply, or does it draw power directly from the measured line?

This voltmeter is self-powered — it draws its operating power directly from the AC line being measured (30–500VAC), so no separate auxiliary power supply is needed. Simply connect the two measurement terminals to the live and neutral (or line-to-line) conductors and the display activates automatically.

Is this voltmeter suitable for outdoor use or only for indoor panel installations?

This unit is designed primarily for indoor panel and enclosure mounting. It does not carry an IP65 or weatherproof rating, so direct exposure to rain, moisture, or dust is not recommended. For outdoor applications, it should be housed inside a sealed IP-rated enclosure to ensure safe and reliable operation.
