Fluke 772

Fluke 772 – Overview

The Fluke 772 is a loop meter/calibrator offering measurement and sourcing of 4-20 mA control signals without breaking the loop. Equipped with a detachable clamp, it simplifies field work in tight spaces by allowing clamp-on measurement. It includes loop power for powering transmitters, auto ramp/step output modes, and dual display to show both mA value and % of span. Designed for process control, maintenance, and calibration tasks where speed and accuracy matter.

Key Features

• Measures 4-20 mA signals without breaking the loop using the clamp

• Sources / simulates 4-20 mA signals for testing I/O or I/P devices

• Dual backlit display shows mA and percent of span simultaneously

• Detachable clamp with extension for tight or hard-to-reach wiring

• Auto ramp & 25 % step output modes

• Loop power (24 V) for powering transmitters while measuring mA

• Measurement “Spotlight” to illuminate in dim enclosures

• Hold function to freeze changing readings

• Range up to ~99.9 mA non-contact to accommodate older process systems
