All specs

Safety rating (IEC 61010 CAT)
What this means

Under IEC 61010, the category reflects location and transient risk: CAT II for plug-in equipment, CAT III for building wiring and panels, CAT IV for the service entrance and utility supply. The voltage is the working voltage at that category. The lowest-rated part (meter, leads or probe) sets the limit.

CAT IV 600 V
AC voltage, max range
What this means

This is the highest AC voltage the meter can display. It should comfortably exceed what you test, such as 120/240 V US residential or 277/480 V commercial. The measurement range is not the safety rating; check the CAT rating for where the meter may be used.

600 V
DC voltage, max range
What this means

This is the highest DC voltage the meter can display, relevant to batteries, controls, solar arrays and automotive work. Solar strings can run well above residential voltages, so check the range covers your systems. As with AC, the range is separate from the CAT safety rating.

600 V
Batteries (cells)
What this means

This lists the cells the meter or tester runs on, such as AA, AAA or 9 V. Common sizes are easy to find on the job. A low battery can cause inaccurate readings on some meters, so replace cells when the low-battery indicator shows.

Alkaline (AAA)
Backlit displayYes

Ratings are Milwaukee's published figures from its US product page, listed under Sources. Anything not on that page is left out rather than guessed. Check this against another model.
