Fluke 772

Key features

  • Loop calibrator that measures 4 to 20 mA signals without breaking the loop
  • Features best in class 0.2% accuracy
  • Simultaneously measures the mA signal with the clamp and sources a mA signal
  • Delivers 0.01 mA resolution and sensitivity
  • Measures mA signals for PLC and control system analog I/O

Product overview: Fluke 772 Milliamp Process Clamp Meter

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

The Fluke 772 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
