3000A True RMS AC High Current Clamp MeterFeaturing a whopping 3000A measurement capability, the design is a little different from a typical clamp meter. Instead of having a set of "jaws" it has a flexible loop that unclips on one side. Run it around your cable then lock it back into the unit. Features min max and data hold, and a backlit LCD. It's CATIII 1000V and CATIV 600V rated. Features autoranging to maximise resolution at low currents too.
