Technical Data

Measurement capability

• 1000 A ac and dc current

measurement with ﬁxed jaw

• 2500 A ac current measure-

ment with iFlex™ ﬂexible

current probe

• 1000 V ac and dc voltage

measurement

• True-rms ac voltage and

current for accurate measure-

ments on non-linear signals

• Frequency measurement to

500 Hz with both jaw and

iFlex™

• 60 kΩ resistance mea-

surement with continuity

detection

• Min, max, average and inrush

recording to capture varia-

tions automatically

Features

• Wireless technology allows

the display to be carried up to

30 ft away from the point of

measurement for added ﬂex-

ibility without interference

with measurement accuracy

• iFlex™ ﬂexible current probe

expands the measurement

range to 2500 A ac while

providing increased display

ﬂexibility, ability to measure

awkward sized conductors

and improved wire access

• CAT IV 600V, CAT III 1000 V

safety rating

• Integrated low pass ﬁlter

and state of the art signal

processing allows for use

in noisy electrical environ-

ments while providing stable

readings

The ﬁrst clamp meter with a detachable, remote

display for easier, faster, safer measurements

381 Remote Display True-rms

AC/DC Clamp Meter with iFlex™

The new Fluke 381 does everything you would expect from a

clamp meter, and then lets you remove the display for even more

ﬂexibility. Now one technician can do jobs that used to require

two people; clamp the Fluke 381 around a conductor, remove the

display and walk across the room to operate controls or remove

protective equipment, all while watching real-time readings. The

new iFlex™ ﬂexible current probe (included) expands the mea-

surement range to 2500 A ac while providing increased display

ﬂexibility, ability to measure awkward sized conductors and

improved wire access.
