Fluke 709H Precision Loop Calibrator with HART Communications / Diagnostics
The Fluke 709H calibrator is built around a user friendly interface with a Quick-Set rotary encoder knob. This tool reduces the time it takes to measure, or source, voltage or current and power up a loop. 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 709H 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)
HART specific capabilities include:
Fast transfer of calibration data: The 709H/Track software/cable documents the parameters of all the HART transmitters in your plant, in either (.csv) or (.txt) format.
Data logging: Record data on a particular transmitter for troubleshooting. The data log tool offers selectable capture interval from 1 to 60 seconds and a logging capacity of 9800 records or 99 individual sessions.
Comprehensive samples: Each data sample contains the 709H measurement, all four process variables, and the standard status conditions.
Communicator Mode: Read basic device information, perform diagnostic tests, and trim the calibration on most HART enabled transmitters without needing a dedicated communicator or laptop.
The Fluke 709H allows virtually any technician to service and support HART devices efficiently in the field.
