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)
