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

Rated 5 out of 5 by WetShaggy from Major Time Saver I've been using this meter for process control at multiple water plants and it has saved a lot of time in troubleshooting issues from new wiring to suspected bad instruments or faulty analog PLC modules. Not having to take the time to pull a wire and hook a meter in series or even the mental calculations to convert 1-5v with a 250ohm resistor to current is great. We had a problem with the plastic clamp shortly after buying it. The hinge broke but Fluke was quick to provide a replacement instrument. Being able to quickly supply current to a loop has also been invaluable. Productivity is the name of the game and this unit helps us get things up and running faster. It has indeed paid for itself.

Rated 4 out of 5 by malex9999 from Excellent Controls Meter I purchased this meter to check milliamp outputs for process control systems. This meter works great for a not-contact meter. It is nice to be able to trouble shoot if the signal is making it to my control device without having to break into the circuit. Only thing preventing a five start rating is the price.

Rated 5 out of 5 by karlkaiser from Usefull meter We got this meter for our agriculture equipment that has 4-20mA sensors on it and it works great to trouble shoot and diagnose the machine.

Rated 5 out of 5 by Fluke Follower from Great commissioning meter The great feature about this meter is that you can measure a mA signal without breaking the circuit. It is also very useful troubleshooting mA output signals. It's been a great aide and time saver in instrument commissioning. It makes it very easy to simulate analog inputs prior to instrument installation. I would recommend this product to anyone that has several 4 -20 mA instruments to maintain.

Rated 2 out of 5 by shouldhavelookedcloser from a little overpriced i bought this meter in the $700 range. the only awesome feature is that you can measure a mA signal without breaking the circuit. other than that, i would not recommend this product. what i find particularly disappointing is that you cannot fully troubleshoot a mA circuit with this tool. without being able to read voltage with this tool, you are not able to tell whether you have an open circuit or no power. i am troubled by the fact that you need to buy the top-of-the-line meter to fully troubleshoot a mA circuit.
