Quick answers

What is the 325'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 325 measure DC current?

Yes: Fluke lists a DC current range up to 400 A.

Is the 325 true-RMS?

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

Does the 325 come with test leads?

Yes: TL75 Test Leads.
