The Extech 380942 is an introductory-level true RMS clamp meter that's small in size and great for testing smaller, more difficult-to-reach conductors. The true RMS technology integrated into this meter ensures that distortion doesn't have an effect on the readings taken by the meter.
Capable of carrying both high accuracy and high resolution measurements, the Extech 380942 excels despite its tiny size. In terms of measurements this product is able to measure AC current to 30A, DC current to 30A and AC/DC voltage up to 400V.
The jaws of this mini clamp meter are 0.9" (23mm) in size, which means they aren't suitable for use on larger conductors. Once attached to a conductor the device will relay information about the test to the devices' 4000 count LCD screen as both a numerical reading and a representation on a fast 40 segment analogue bargraph.
Additional features of this clamp meter included one touch auto zeroing, data hold function and MAX/MIN recall display.
This clamp meter is EN 61010-1 compliant and CAT III 300V safety rated.
