Product Overview

The Fluke 772 Milliamp Process Clamp Meter is a highly efficient troubleshooting tool for 4–20 mA process control loops, designed to help instrumentation technicians work faster and safer. It allows accurate mA measurements without breaking the loop, eliminating downtime and avoiding disruption to critical control processes.

In addition to clamp-on mA measurement, the Fluke 772 can measure, source, and simulate mA signals, and it provides 24 V loop power for testing and powering transmitters. Built for industrial environments, it is ideal for maintaining and commissioning transmitters, PLC/DCS I/O, valves, and other process instrumentation.

Key Features

• Measure 4–20 mA Without Breaking the Loop – Clamp-on measurement saves time
• mA Measure, Source & Simulate – Complete loop troubleshooting in one tool
• In-Circuit mA Measurement – Measure directly with test leads when required
• 24 V Loop Power – Power and test transmitters without external supplies
• Linear Ramp & 25% Step Output – Automated signal changes for remote testing
• High Accuracy mA Measurement – Reliable diagnostics for process systems
• Large Backlit Display – Easy reading in plant and panel environments
• Power-Saving Features – Auto power-off and backlight timeout
• Rugged Industrial Design – Built for daily use in process industries
