Ready For Anything
Fluke 740 Series Documenting Process Calibrators:
Work Smarter. Work Faster.
Whether you’re calibrating instruments,
troubleshooting a problem or running
routine maintenance, Fluke 740 Series
process calibrators can help you get
the job done faster. It does so many
different tasks, so quickly and so well,
it’s the only process calibrator you need
to carry.
• Multifunctional. Calibrate
temperature, pressure, voltage, current, resistance, and frequency. Since
it both measures and sources, you can
troubleshoot and calibrate
all with one rugged tool.
• Powerful, yet easy to use. The
easy-to-follow, menu-driven display
guides you through any task. Programmable calibration routines enable you to create and run automated
as-found/as-left procedures to ensure
fast, consistent, calibrations.
• Records and documents results.
To support your ISO-9000 or regulatory standards, the Fluke 741B, 743B,
and 744 capture your calibration
results, eliminating the need to juggle
a pen and pad in the field. The
RS-232 interface in the Fluke 743B
and 744 lets you transfer the results
to a PC, thus saving the time of having to manually transcribe them when
you return to the shop.
• Supports popular instrumentation
management software. The 743B
and 744 work with the Fluke DPC/
TRACK™ software, and with popular
programs from Honeywell Loveland,
Cornerstone, Yokogawa, Prime Technologies, On-Time Support, and others.
It allows you to create procedures,
instructions, and action lists to deliver
fast, easy documentation.
• Truly hand-held. Small enough to
fit easily into a tool bag and to use in
tight spaces. Runs an entire shift on
a rechargeable NiCd or NiMH battery
pack.
• Rugged and reliable. Overmolded
urethane case stands up to rough
handling in industrial environments.
Calibrators offer one- or two-year
calibration cycles and three-year
warranty.
• Bright white display lets you read
your results in any kind of light.
• Soft keys provide one-touch ac-
cess to enhanced functions such as
task lists, automated procedures,
scaling, min/max, stepping and
ramping, and review memory.
• Three operating modes Measure,
Source, or simultaneous Measure/
Source, — enable technicians to
troubleshoot, calibrate, or maintain
instrumentation with just one tool.
• Integrated HART communication
capability lets you program and
control HART instrumentation
(744 only).
• Multi-lingual interface displays
instructions in English, French, German, Spanish, and Italian.
• AutoStep allows technicians to set
the calibrator for a delayed start
and a specific sequence of steps, so
it can run unattended as a continuously varying test source.
• User entered values enable users
to capture readings measured or
sourced by other devices.
• Custom units allow readings to be
scaled and displayed in any userdefined units.
• Limit switch calibration
procedures perform fast,
automated calibration of one-
and two-point limit switches for
voltage, current, temperature,
and pressure.
• Differential pressure flow instru-
ment calibration routines use a
square root function
to directly calibrate DP flow instruments.
• Built-in algebraic calculator
with four functions — plus square
root—stores, recalls, and performs
calculations required for setting up
instruments or evaluating data in
the field. Use it to set the source
function to a calculated value.
There’s no need to carry a pencil
and paper or a separate calculator.
• Programmable measurement
delay inside automated
procedures permits calibrating
instruments that respond slowly.
Two bonus features available
with product registration:
• Transmitter mode
• Bar code entry (except 741B)

Fluke 740 Series Documenting Process Calibrators:
Calibrators as versatile as you are.
The Fluke 740 Calibrators, offered in three models, let
you choose the right set of capabilities for your needs.
• The Fluke 741B offers simultaneous source
and measure capabilities for all common process parameters. Create and execute automated procedures
and automatically capture the results.
• The Fluke 743B offers all the capability of the 741B,
plus adds a serial interface for two-way communication with popular PC-based instrumentation
management applications.
• The Fluke 744 offers all of the capabilities of the
743B, plus the ability to maintain and calibrate
selected HART transmitters without a second tool.

Fluke 744 HART Documenting Process Calibrator:
Get HART-ability.
As more and more process plants begin to take
advantage of smart transmitters, the need for a new
generation of calibrators has emerged— calibrators
that can communicate via industry standard digital
protocols. The 744 combines HART communication
capability with the popular 740 Series Documenting
Process Calibrators to deliver an integrated communicating calibrator. This rugged, reliable tool is ideal for
calibrating, maintaining, and troubleshooting HART
instrumentation. The 744 offers:
• Integrated HART communication functions, permitting you to monitor, control, and calibrate HART
instrumentation.
• Handling of fast pulsed RTD transmitters and PLCs,
with pulses as short as 1 mS.
NiMH battery with 3500 mA hour life and gas gauge.
•
The first field calibrator for HART instruments
that’s both powerful and easy to use.
The 744 offers the most complete HART implementation of any process calibrator. The 744:
• Requires no external box or second tool for everyday HART calibration and maintenance.
• Offers fast HART communication.
• Supports popular models of HART transmitters, with
more device-specific command support than any
other HART field calibrator.
• Fully complies with the Data Link Layer of the HART
protocol, including multiple masters, burst mode,
and multi-drop configurations.
• Is easy to update as additional instruments are
added and new HART versions are released.
• Is based on the 743B, the most rugged, reliable
multifunction field calibrator available.
• Is backed by the service and support of the Fluke
organization, a member of the HART Communications Foundation.
The 744 is designed to take on nearly all the day-today tasks you now perform with a separate communicator. In fact, it offers the communication capabilities
of the 275 HART communicator except for the DD
interpreter, which can read command set libraries
from any HART supplier. This is not necessary for daily
HART maintenance.

interrogating HART devices.
• Read HART PV function and smart transmitter digi-
tal output while measuring analog mA output.
• Read and write HART configuration functions to
make field adjustments to PV range points, damping,
and other top-level configuration settings.
• Change sensor configuration on supported
temperature transmitters.
• Re-label smart transmitters by reading and writing
HART tag and message fields.
• Clone additional transmitters by reading and
