Documenting Process Calibrator HART Mode
Introduction
w Warning
To avoid electric shock, read the Safety
Information in the
744 Users Manual before
you use the Fluke 744 Documenting Process
Calibrator.
With analog transmitters, you must make a hardware
adjustment during calibration. With HART

(Highway-
Addressable Remote Transducer) transmitters,
adjustments are by remote command. These adjustments
require the use of a communication tool as well as a
calibrator. The Fluke 744, hereafter called “calibrator,”
provides communication and calibration functions in one
tool.
This manual describes how to use HART mode, which is
active when the calibrator is communicating over its serial
HART interface to a HART transmitter. Refer to the
744 Users Manual for safety, analog mode operating
instructions, specifications, and other general information.
All of the calibrator functions described in the
744 Users
Manual are available and can be used with HART
transmitters. The only transmitters addressed in this
manual are HART transmitters.
