The TEK 632 is the first in a series of two “Mini” Clamp Meters which are designed to verify the presence of load current and non contact voltage. The TEK 632 is probably one of the lowest priced AC/DC “Mini” Clamp Meters currently available! The small body and jaws fit perfectly into your hand and feature a large back lit display, together with a built in jaw “flashlight” which illuminates the jaw opening around cables.
