Frequently asked questions
Everything you might want to know before you order.
What voltage and current ranges does this multimeter measure?
It measures AC/DC voltage up to 600V and AC/DC current up to 4A, covering common electrical testing needs.
What does True RMS mean for my measurements?
True RMS provides accurate readings on non-linear loads, so you get reliable values even when the waveform is distorted.
How does non-contact voltage (NCV) detection work?
NCV detection lets you quickly check for the presence of voltage without making direct contact, adding safety and speed to your checks.
Can I switch between auto-ranging and manual mode?
Yes, the multimeter is auto-ranging with a manual mode override, giving you flexibility to lock in a specific range when needed.
Is the display easy to read in low light?
The large LCD is backlit, and a built-in flashlight helps you work in dimly lit areas, with data hold and low battery indicators for convenience.
