Milliamp mA Loop CalibratorsFLUKE 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

Milliamp mA Loop CalibratorsFLUKE 709H Precision mA Loop Calibrator with HART Communications / Diagnostics
The Fluke 709H mA loop calibrator is designed to save time and produce high-quality results. It includes HART communication and supports a select set of the HART universal and common practice commands. This makes the 709H unique as both an affordable, compact loop calibrator and powerful HART communication tool that offers:
- Fast transfer of calibration data:The optional 709H/Track software/cable can document the parameters of all the HART transmitters in your plant, in either (.csv) or (.txt) format
- Data logging or recording data on a particular transmitter for troubleshooting: The data log tool offers a selectable capture interval from 1 to 60 seconds and a logging capacity of 9800 records or 99 individual sessions. Each data sample contains the 709H measurement, all four process variables, and the standard status conditions.
In the communicator mode the user can read basic device information, perform diagnostic tests, and trim the calibration on most HART-enabled transmitters. In the past, this could only be done with a dedicated communicator, a high-end multifunction calibrator, or a laptop computer with HART modem. The Fluke 709H will allow virtually any technician to service and support HART devices.
And it’s easy to use. The Fluke 709H is built around a user-friendly interface with a Quick-Set rotary encoder knob. This reduces the time it takes to measure or source voltage or current, and power up a loop. The protective holster easily fits into a technician’s hand and the large backlit display is easy to read, even in dark, cramped worked areas.
Other useful features:
- Provides resolution of 1 µA on mA ranges and 1 mV on voltage ranges
- Quickly transfers calibration data for documentation in either (.csv) or (.txt) format with optional 709H/Track software/cable
- Offers selectable capture interval from 1 to 60 seconds and a logging capacity of 9800 records or 99 individual sessions.
- Features small rugged design and runs on six standard AAA batteries
- Requires only simple two wire connection for all measurements
- Provides Auto Shutdown to conserve battery life (adjustable up to 30 minutes)
- Offers variable step and ramp time in seconds
- Provides adjustable span selection (0 to 20 mA or 4 to 20 mA)
- Includes valve test functionality (simulate defined mA values with % keys)
