Technical Data
Fluke 355/353
True-rms 2000 A Clamp Meters
High current and
a large jaw, make
these clamps
well suited for
industrial and
utility applications
Confidently take reliable readings
with the true-rms, Fluke 355/353
Clamp Meters; the tools of choice
for high-current measurements
up to 2000 A. The extra-wide
jaw easily clamps around large
conductors typically found in high-
current applications. The rugged
design and CAT IV 600 V, CAT III
1000 V ratings, add an extra ele-
ment of protection when taking
high-powered measurements.
Accurate peak measurements
can be taken using the in-rush
current mode, ideal for motors
and inductive loads. The 355 also
measures voltage and resistance,
making this the most versatile tool
for utilities, electrical contractors,
and industrial service technicians.
•Reliably handle a wide range of high-current
applications with 2000 A ac + dc true-rms,
1400 A ac, and 2000 A dc
•The large 58 mm (2.3 in) jaw capacity is suitable for
large, or multiple conductors
•CAT IV 600 V, CAT III 1000 V rating for added user
protection
•In-rush current measurement captures ‘power-on’
surge current with accuracy and repeatability
•High voltage measurement of 1000 V ac + dc
true-rms, 600 V ac, and 1000 V dc allows users to
perform multiple tests with only one tool (355 only)
•Resistance to 400 kWcoupled with a continuity
beeper, provide the convenience of a multimeter
(355 only)
•Accurately measure frequency up to 1 kHz for
optimum troubleshooting
•Quickly analyze readings using the MIN, MAX, and
AVG functions
•A large backlit display allows for easy visibility in
low-lit areas
•Use the display hold feature to capture readings
even when the display cannot be viewed
•Use the low-pass filter to smooth out noisy loads
and stabilize readings
