Quick answers

What is the 323's safety (CAT) rating?

Fluke rates it CAT III 600 V, CAT IV 300 V. CAT IV covers the service entrance and utility side, CAT III distribution-level circuits such as panels and feeders; the lower of the meter's and the test leads' ratings is the one that applies. See our <a href="/cat-ratings-explained/">CAT ratings guide</a>.

Does the 323 measure DC current?

Fluke's spec table lists AC current (up to 400 A) and no DC current range.

Is the 323 true-RMS?

Yes, Fluke lists it as true-RMS, so readings on non-sinusoidal loads (drives, dimmers, electronic ballasts) are not averaged.

Does the 323 come with test leads?

Yes: (1 pair) Test leads.
