The Fluke 709H will allow virtually any technician to service and support HART devices.
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:
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.
