The Fluke 330 Series Clamp Meters offer
all the features you need to fit the way
you work. The small body and jaws fit
perfectly in your hand and into tight
places. Meter controls are positioned so
that current measurements can be done
with one hand. A large backlit display
(on most models) is easy to see and a
handy Display Hold keeps measurements
on the display. Measuring starting current
for motors, lighting, etc. is easy with the
in-rush current function (on most
models). All models are backed up with a
3 year warranty.
