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 tool.
The Fluke 709H mA loop calibrator is designed to save time and produce high-quality results. These calibrators are 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 protective holster easily fits into a technician's hand and the large backlit display is easy to read, even in dark, cramped worked areas.

In the communicator modethe user will be able to readbasic device information, performdiagnostic tests, and trim the mAoutput on most HART enabledtransmitters. In the past, this couldonly be done with a dedicatedcommunicator, a high-end multifunctioncalibrator, or a laptopcomputer with HART modem.Fluke 709H will allow virtuallyany technician to service and supportHART devices.
