Fluke 772 – Milliamp Process Clamp Loop Meter

• Measures 4–20 mA signals without breaking the loop
• Sources and simulates 4–20 mA signals for process testing
• Provides 24 V loop power for transmitter testing
• Measures mA in-circuit through test leads or clamp jaw
• Supports automatic linear ramp and 25% step outputs

The Fluke 772 Milliamp Process Clamp Loop Meter combines loop measurement and signal generation in a single handheld instrument. Fluke designed it for process technicians who need to troubleshoot, test, and maintain control systems without interrupting operations.

The Fluke 772 measures 4–20 mA signals without breaking the loop. As a result, users can diagnose transmitter and control system issues while avoiding costly downtime.

In addition to clamp measurements, the instrument measures mA directly through test leads. Therefore, technicians can verify process signals using the method best suited to the application.

The Fluke 772 can source and simulate 4–20 mA signals for testing control system inputs, outputs, and I/P devices. Furthermore, the integrated 24 V loop power supply allows users to power and test transmitters from a single instrument.

Automatic linear ramp and 25% step output functions simplify remote testing and calibration procedures. In addition, the clear backlit display improves visibility when working in plant environments and control panels.

Its rugged portable design withstands demanding industrial conditions while remaining easy to carry throughout the working day. For professionals who require reliable loop measurement and calibration capabilities, the Fluke 772 offers a practical solution for process maintenance and troubleshooting.
