Process Calibrators:
Ready for anything
Technical Data
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/asleft 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 Tech-nologies, OnTime 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 access 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 oneand 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)

740 Series
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.

744 upgrades available
Fluke periodically releases new internal software for
the Fluke 744. These upgrades include:
• New revisions of previously supported instruments.
• Device-specific command support for new
instruments.
• New HART communication capability.
The upgrade can be easily loaded from a PC to a 744.
What’s new in Version 2.5
Device-specific calibration
•
support for new instruments:
• Micro Motion 2000, 2000 IS,
9701, 9712 and 9739 coriolis
flow transmitters
• Fuji FCX and FCXA2 pressure and
FRC temperature transmitter
• New features:
• Support for New Hart Scientific dry blocks:
7103, 9007, 9011, 9023, 9103, 9105, 9107,
9122, 9127, 9132, 9133 and 9150
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 every-
day 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.
