Quick answers
What is the MM720's safety (CAT) rating?
Klein Tools rates it CAT IV 600 V, CAT III 1,000 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 MM720 measure DC current?
Yes: Klein Tools lists a DC current range up to 10 A.
Is the MM720 true-RMS?
Yes, Klein Tools lists it as true-RMS, so readings on non-sinusoidal loads (drives, dimmers, electronic ballasts) are not averaged.
What batteries does the MM720 use?
2 x AAA (dry cells; no tool battery platform).
Does the MM720 come with test leads?
Yes: Test Leads with CAT III/CAT IV Safety Caps.
