Frequently asked questions
What does a CAT rating mean?
CAT (Category) ratings indicate how much transient voltage spike a meter is rated to safely withstand. CAT III 600V is the standard recommendation for home electrical panels and most residential wiring work.
Do I need True RMS?
True RMS matters if you're measuring non-sinusoidal signals — common with modern electronics, variable-speed motors, and dimmer switches. For basic DC continuity checks, it's less critical.
