744: Get HART-ability
The Fluke 744 offers all of the capabilities of the 743B, plus
the ability to calibrate, maintain, and troubleshoot HART
instrumentation. Integrated HART communication functions
permit you to monitor, control, and calibrate HART instru-
mentation. It handles fast pulsed instruments such as RTD
transmitters and PLCs, with pulses as short as 1 ms.
See www.fluke.com/744upgrade for the latest list of
HART instruments.
743B: More memory, plus a PC interface
and data logging
The 743B has all the capabilities of the 741B plus a PC
interface that lets you load procedures, lists, and instructions
created with software – or unload data for printing, archiving,
and analysis. With its expanded memory, the 743B can hold
a full week of calibrations and procedures.
741B: A complete documenting calibrator
The 741B is the economical choice for plants that don’t use
PCs or that require traditional paper forms. It has storage
capacity for a day’s calibration and measurement data. When
you’re back at the shop, recall the data on-screen to fill out
calibration forms.

HART®Transmitter Calibration
Application Note
(Literature code 1262439)
The need for calibration of HART
smart transmitters is often misunder-
stood. What do you calibrate and
when? Here is a step-by-step proce-
dure showing how to use the Fluke
744 to perform calibration and digital
adjustments of Rosemount 3051 and
3144 transmitters and other HART
devices.
