Fluke Clamp Meters: Which One is Right for You?

Clamp meters allow electricians to bypass the old-school method of cutting into a wire and inserting a meter's test leads into the circuit to take an in-line current measurement. The jaws of a clamp meter do not need to touch a conductor during a measurement - neither is it necessary to shut off the circuit carrying current , which is a big boost in efficiency.

FEATURED METER: 377 FC Non-Contact Voltage True-rms AC/DC Clamp Meter with iFlex

Voltage and current measurements with FieldSense technology

The Fluke 377 FC true-rms clamp meter uses FieldSense technology to make testing faster and safer, all without contacting a live conductor. Users get accurate voltage and current measurements through the clamp jaw. Simply clip the black test lead to any electrical ground, put the clamp jaw around the conductor and see reliable, accurate voltage and current values on the display.

Measure extremely high current with iFlex probe

Use the included iFlex flexible current probe to measure ac current as high as 2500 A. The iFlex probe provides access to large conductors in tight spaces.

Complete 3-phase measurements

• Complete 3-phase voltage and current tests in 3 easy steps
• Full set of phase-to-ground and phase-to-phase values calculated and shown on the meter
• Values are also displayed on your smart phone and saved to the cloud via Fluke Connect software
• Phase rotation auto-calculated and shown on the Fluke Connect software
• No more hand-written notes or complicated math

Easy to see, easy to use with included tools

Jobs will get easier when using the 377 FC clamp meter. The display turns green when a stable FieldSense measurement is detected. Visual Continuity also provides a bright green screen for easy detection of continuity in noisy work areas.

Record, analyze, share results with Fluke Connect software

With Fluke Connect software you can remotely log, trend and monitor measurements to pinpoint intermittent faults. Fluke Connect also allows you to gather data as the basis for a preventive maintenance program.

Clamp meters are used on industrial equipment, industrial controls, and residential/commercial/industrial electrical systems. They are primarily used for:

• Service: To repair existing systems on an as-needed basis
• Installation: To troubleshoot installation problems, perform final circuit tests, and supervise apprentice electricians while installing electrical equipment
• Maintenance: To perform scheduled and preventative maintenance as well as system troubleshooting

FEATURED METER: Fluke 355 True RMS 2000 A Clamp Meter

Versatile and rugged clamp meter for high currents

Confidently take reliable readings with the True RMS Fluke 355 digital clamp meter, the tool of choice for high current clamp-on amp meter measurement up to 2000 A. The extra-wide jaw easily clamps around large conductors, typically found in high-current applications. The extra rugged design and CAT IV 600 V, CAT III 1000 V ratings add an extra element of user 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 an ideal clamp meter for utilities, electrical contractors and industrial service technicians.

Easy to use all-in-one tool

• High voltage measurement of 1000 V AC + DC True RMS, 600 V AC, and 1000 V DC allows users to perform multiple tests with one tool

Add a Fluke industrial clamp meter to your toolbox:

Other specialty tools are associated with the clamp meter category. Fluke’s product line addresses a variety of specific troubleshooting issues with clamp-based tools. Originally created as a single-purpose test tool, modern clamp meters offer more measurement functions, greater accuracy and in some cases specialized measurement features.

FEATURED METER: 1630-2 FC Earth Ground Clamp

The 1630-2 FC clamp measures earth ground loop resistances for multi-grounded systems using the dual-clamp jaw. This test technique eliminates the dangerous and time-consuming activity of disconnecting parallel grounds, as well as the process of finding suitable locations for auxiliary test stakes. You can also perform ground tests in places that were previously difficult: inside buildings, on power pylons or anywhere you don't have access to soil to place auxiliary test stakes.

Earth ground ac leakage current measurement

• Identify ac leakage currents without disconnecting earth ground stake from grounding system
• Rugged heavy-duty clamp jaw stays in alignment and in calibration, even in everyday, on-the-job industrial environments

Logging measurements

• Earth ground clamp saves time by automatically recording data at preset intervals
• Saves up to 32,760 measurements at set logging intervals
• Saves time by recording and storing measured values

Alarm threshold: User-defined high/low alarm limits for rapid measurement evaluation

Band-pass filter: Selectable band-pass filter function removes unwanted noise from ac leakage current measurements

Fluke Connect Wireless System

• 1630-2 FC connects with app on smart devices (may not be available in all regions)
• Save measurements and images to Fluke Connect Cloud storage and share with teams
• Maximize uptime and make confident maintenance decisions with trusted, traceable data
• Access baseline, historical and current measurements by asset
• Share measurement data using ShareLive video calls and emails
