Fluke 771 – Milliamp Process Clamp Meter

• Measures 4–20 mA signals without breaking the loop
• Best-in-class 0.2% accuracy with 0.01 mA resolution
• Measures analogue I/O signals in PLC and control systems
• Detachable clamp for easier access in confined spaces
• Dual backlit display with percentage-of-span indication

The Fluke 771 Milliamp Process Clamp Meter allows technicians to measure 4–20 mA signals without breaking the loop. As a result, users can troubleshoot process systems without interrupting operations or causing costly downtime.

The Fluke 771 delivers 0.2% accuracy and 0.01 mA resolution. In addition, it measures low-level DC current signals used in transmitters, PLCs, and process control equipment.

Its detachable clamp makes measurements easier in confined spaces. Therefore, technicians can position the clamp on the conductor and view readings from a more convenient location using the extension cable.

The dual backlit display shows both the measured mA value and the percentage of the 4–20 mA span. Furthermore, this feature allows users to assess loop performance quickly during maintenance and commissioning tasks.

A built-in LED spotlight improves visibility inside dark control panels and enclosures. The Hold function also captures unstable readings, making measurement recording and verification more straightforward.

The compact lightweight design supports everyday field use, while battery life of up to 40 hours helps maximise productivity. For professionals who maintain process instrumentation, the Fluke 771 provides a fast and reliable solution for loop measurement and troubleshooting.
