Fluke 374 Manual de usuario

Technical Data

Measurement capability

• 600 A ac and dc current

measurement with ﬁxed jaw

• 2500 A ac current mea-

surement with iFlex™

ﬂexible current probe (sold

separately)

• 600 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™ (Fluke 375 only)

• Resistance measurement to

60 kΩ (Fluke 375) or 6000 Ω

(Fluke 374) with continuity

detection

• Min, max, average and inrush

recording to capture varia-

tions automatically

• 500 mV dc measurement

range to interface with other

accessories (Fluke 375 only)

• 1000 µF capacitance

measurement

Features

• 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

(Fluke 375 only) and state

of the art signal process-

ing allows for use in noisy

electrical environments while

providing stable readings

Work horse clamps with increased

performance and ﬂexibility

374 and 375 True-rms

AC/DC Clamp Meters

The new Fluke 374 and 375 clamp meters offer improved

performance perfect for many current measurement situa-

tions. With true-rms ac voltage and current measurements,

the Fluke 374 and 375 can read up to 600 V and 600 A in

both ac and dc modes. Additionally, both are compatible with

the new iFlex™ ﬂexible current probe (sold separately) which

expands the measurement range to 2500 A ac and pro-

vides increased display ﬂexibility, ability to measure around

awkward sized conductors and improved wire access.

2 Fluke Corporation 374 and 375 True-rms AC/DC Clamp Meters

• Proprietary inrush measure-

ment technology to ﬁlter

out noise and capture motor

starting current exactly as the

circuit protection sees it

• Ergonomic design ﬁts in your

hand and can be used while

wearing personal protective

equipment

• Large, easy to read, backlight

display automatically sets the

correct measurement range

so you do not need to change

switch positions while taking

a measurement

• Three-year warranty

• Soft carrying case
