Product Description

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 ? 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)
