Fluke 709H, Loop Calibrator

The Fluke precision loop calibrator reduces the time it takes to measure or source voltage or current and power up a loop. It is used for installation, calibration and troubleshooting field transmitters, valves and other control system components. Its primary function is to source and measures mA signals in the range of 0mA to 24mA. This loop calibrator can measure 0V to 30V and produce 24VDC loop power. This device includes HART communication functionality and supports a selected set of HART universal and common practice commands. It can be used as a loop calibrator or basic function communicator. It is supplied with AC72-1 alligator clips (2), TL75 test leads, soft case, 6 AAA batteries (installed), product manual, quick reference guide and a safety information manual. The calibrator offers the ability to store up to twenty HART device configuration files for uploading via 709H/TRACK software via the 709H/TRACK software. Configurations can be stored as .CSV or .TXT files. This allows the end-user to document plant HART easily.
