Fluke 709 Precision Loop Calibrator The Fluke 709 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. Primary functions are source and measure mA signals in the range 0 to 24 mA. The Fluke 709 can measure 0 to 30 V and produce 24Vdc loop power. The 709H includes HART communication functionality and supports a select set of HART universal and common-practice commands. It can be used as a loop calibrator or basic function communicator.
