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.
