Frequently Asked Questions
What does true RMS mean on this multimeter?
▾
True RMS measures AC voltage and current accurately, even with distorted or non-sinusoidal waveforms. This ensures reliable readings on modern electronics, motors, and variable-speed drives, unlike average-reading meters that can be off by up to 40%.
Does this multimeter measure both AC and DC voltage?
▾
Yes, it measures AC and DC voltage with a range up to 600V. This makes it suitable for testing household outlets, car batteries, and electronic circuits. The auto-ranging feature simplifies switching between types and scales.
How does the continuity test work?
▾
The continuity test checks if a circuit is complete. When probes touch both ends of a conductor, the meter beeps if the path is unbroken. This helps quickly locate broken wires or verify connections during repairs.
Is the AstroAI multimeter safe for home electrical work?
▾
Yes, it's CAT III 600V rated, meaning it's designed to safely handle voltage spikes in residential power systems. This certification ensures protection when testing outlets, breakers, and junction boxes in homes and small buildings.
