The Fluke 709H Precision HART
Loop Calibrator is an easy-to-use
tool with user-friendly interface and
HART capabilities that reduces the
time it takes to measure or source,
voltage or current, and power up a
loop. With accuracy at 0.01% of
reading, it is suitable for process
technicians who need a precise loop
calibrator and powerful HART
communicator in one compact tool.

The Fluke 709H supports a select
set of HART universal and common
practice commands. In communicator
mode, technicians can read basic
device information, perform
diagnostic tests, and trim the
calibration on most HART-enabled
transmitters. It also has a built-in,
selectable 250-ohm resistor to tune
the loop for HART communications.
