Description
Product overview: Fluke 772 Milliamp Process Clamp Loop Meter
Fluke 772 Milliamp Clamp Loop 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
