Fluke 709 Precision mA Loop Calibrator
Model No :
Fluke 709
Part Code :


The Fluke 709 mA loop calibrator reduces the time it takes to measure or source voltage or current and power up a loop and still produce high-quality results. It's built around a user friendly interface with a quick-set rotary encoder knob and best in class accuracy at 0.01% of reading.

- mA precision loop calibrator with best-in-class accuracy at 0.01% reading
- Provides intuitive user interface with quick-set rotary encoder knob for fast setup
- Includes built in selectable 250 O resistor for HART communication
- Features 24 V DC loop power with mA Measure Mode (-25% to 125%)
- Requires only simple two wire connection for all measurements
