## More about Klein Tools Test & Measurement

Klein test and measurement covers the diagnostic spine of trade work: non-contact voltage testers (NCVTs) for quick presence-of-voltage checks, multimeters for measured values, clamp meters for in-circuit current, and dedicated testers for receptacles, GFCIs, and continuity. Match the CAT rating to the system you're testing.

**Which Klein meter do most electricians start with?**
The MM400 / MM600 auto-ranging multimeter and an NCVT pen cover 90% of residential and light-commercial work. Add a CL clamp meter (CL220, CL390) when you start measuring load current without breaking the circuit.
**What's the difference between an NCVT and a multimeter?**
An NCVT detects an energized AC field without contact — fast yes/no for safety checks. A multimeter measures actual voltage, current, resistance, and continuity in contact with the conductor. Pros carry both — NCVT first, meter to verify.
**Are Klein meters CAT-rated?**
Yes. Klein multimeters and clamp meters carry CAT III 600V or CAT IV 600V / CAT III 1000V ratings depending on model. Match the rating to where you're measuring — service entrance is CAT IV, branch circuits CAT III.
