FLUKE 772 Milliamp Process Loop Clamp Meter measures, sources, and simulates 4-20 mA signals for testing control system I/O or IPs

The Fluke 772 loop meter adds to the basic capabilities of the Fluke 771 to save more time and expand its applications. With the 771, you’ll also be able to: source and simulate 4-20 mA signals for testing control system I/O; measure 4-20 mA signals with in-circuit measurement; power a transmitter with the 24 V loop power supply; and automatically ramp and step change the 4-20 mA output for remote testing.

You’ll be able to test 4–20 mA signals five times faster than with traditional DMMs, and without breaking the loop. That means you can troubleshoot a live device without having to power down, which can save you time, and help you avoid possibly missing something going on in the process.

Other useful features:

Simulates 4-20 mA signals for testing control system I/O
Sources 4 to 20 mA signals for testing control system I/O or I/Ps
Measures 4 to 20 mA signals with in-circuit measurement
Includes simultaneous mA in-circuit measurement with 24V loop power for powering and testing transmitters
Features a detachable clamp with extension cable for measurements in tight locations
Captures and displays changing measurements with Hold function
Offers mA output linear ramp or 25% step output
Extends battery life with auto-off and backlight timeout
Dual backlit display with both mA measurement and percent of 4 to 20 mA span
Measurement Spotlight to illuminate hard to see wires in dark enclosures
Measures 10 to 50 mA signals in older control systems using the 99.9 mA range
Automatically changes the 4 to 20 mA output for remote testing

With the Fluke 771 you no longer need to lift a wire from a terminal (break the loop) to measure 4-20 mA which has a direct impact on your maintenance time. With the Fluke 771 there is no need to call a control room to override the control of a process loop when breaking the loop and you save time when testing analogue I/O on a PLC if you do not need to check measurements on a console. In addition, the Fluke 771 can have another impact on your overall cost by eliminating catastrophic plant outage caused by accidentally opening a critical loop.

Fluke 771 Features:

Measure mA signals for PLC and control system analog I/O
Measure 4 to 20 mA output signals from transmitters without breaking the loop
0.2 % accuracy basic accuracy
Resolution and sensitivity to 0.01 mA
Hold function captures and displays changing measurements
Dual backlit display with both mA measurement and percent of 4 to 20 mA span
Measurement Spotlight illuminates hard to see wires in dark enclosures
Detachable clamp with extension cable for measurements in tight locations
Measure 10 to 50 mA signals in older control systems using the 99.9 mA range
Automatic power off after 15 minutes and 2 minute automatic off for backlight and spotlight
