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 kW coupled 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
