The Fluke 709H Precision Loop Calibrator with HART Communications/Diagnostics is designed to save time and produce high-quality results. This calibrator is built around a user friendly interface with a quick-set rotary encoder knob. This tool reduces the time it takes to measure or source current, and power up a loop. The large, backlit display is easy to read, even in dark, cramped worked areas.

Hart Communications

The 709H adds HART communications 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 troubleshooting tool.

In the communicator mode the user will be able to read basic device information, perform diagnostic tests, and trim the mA output 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 a HART modem. Fluke 709H will allow virtually any technician to service and support HART devices.

Data logged mA loop measurements and HART data can be recorded from a particular transmitter for troubleshooting and loop tuning. The data log feature offers selectable capture with recording intervals of 1 to 60 seconds and a logging capacity of 9800 records or 99 individual sessions. Each data sample contains the 709H mA measurement, all four process variables, and the standard status conditions.
