Fluke 709 Precision Loop Calibrator
The Fluke 709 mA loop calibrator is designed to save time and produce high-quality results. This tool reduces the time it takes to measure, or source, voltage or current and power up a loop.
The Fluke 709 Precision Loop Calibrator is built around a user friendly interface with a Quick-Set rotary encoder knob. 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. The 709 offers:
- Best-in-class accuracy at 0.01% reading
- Small rugged design operates on (6) standard AAA batteries
- Intuitive user interface with Quick-Set knob for fast setup, easy use
- Built in selectable 250 Ω resistor for HART communication
- 24 V DC loop power with mA Measure Mode (-25% to 125%)
- Resolution of 1 µA on mA ranges and 1 mV on voltages ranges
- Simple two wire connection for all measurements
- Auto Shutdown to conserve battery life (adjustable up to 30 minutes)
- Variable step & ramp time in seconds
- Adjustable span selection (0 to 20 mA or 4 to 20 mA)
- Valve Test (simulate defined mA values with % keys)
