The Fluke 771 Milliamp Process Clamp Meter is a clever, time-saving tool that makes troubleshooting 4-20 mA loops a breeze, keeping processes online and costs down. It measures signals without breaking the loop, delivering spot-on readings with 0.2% accuracy and 0.01 mA resolution—perfect for PLCs, transmitters, and control system I/O. The detachable clamp, paired with an extension cable, lets you snake into tight spots and reposition the meter for better viewing, while the dual backlit display shows both mA and the 4-20 mA span percentage at a glance.

A built-in LED spotlight lights up dark enclosures, and the Hold function locks in fluctuating readings for easy verification. With a rugged design that handles 1-meter drops and a 40-hour battery life from two AA batteries, the 771 also tackles 10-50 mA signals in older systems up to 99.9 mA. Backed by a three-year warranty for electronics, this compact meter is a must-have for technicians who want fast, reliable diagnostics with a touch of practical flair.
