Do you need to break the current loop to take measurements?

No, you measure 4 to 20 mA signals directly without breaking the loop or shutting down the system.

What is the measurement accuracy of the Fluke 771?

The clamp meter provides a 0.2 % accuracy with a resolution and sensitivity of 0.01 mA.

Can you take measurements in tight spots?

Yes, the detachable clamp with extension cable allows easy measurement access in cramped control panels.

What measurement ranges does the device support?

In addition to standard 4 to 20 mA loops, it measures 10 to 50 mA signals in older systems via the 99.9 mA range.

What is included in the package?

The Fluke 771 milliamp process clamp meter comes with a soft carrying case and a user manual.

Measure current loops without downtime

Practical benefits

Measure without breaking the loop: You measure 4-20 mA signals directly without interrupting the control loop, saving time and preventing costly system shutdowns during maintenance.
Detachable clamp for tight spaces: The removable clamp with an extension cable lets you easily reach wires in crowded panels and view the display comfortably.
Built-in spotlight for dark enclosures: The integrated LED light illuminates hard-to-see conductors in dark control cabinets for quick and accurate inspections.

In a nutshell

The right choise for

With the Fluke 771 milliamp process clamp meter, you measure 4-20 mA control signals directly on the wire without breaking the current loop. This allows you to troubleshoot plc and dcs analog input and output modules quickly while avoiding costly system downtime. The compact, detachable clamp with an extension cable lets you reach tight conductors inside crowded control panels, while the built-in spotlight illuminates dark enclosures for safe operation. Offering a 0.2 % accuracy and 0.01 mA resolution, it delivers precise diagnostic results on sensitive instrumentation. The Fluke 771 comes complete with a soft carrying case and a user manual, making it ready for every maintenance job.
