Fluke 744: The first HART calibrator that is easy to use.
HART Applications
Versatile HART protocol support
The 744 supports the commands contained in HART
protocol version 5.7. With 2 MB of memory, the 744
supports a substantial set of HART instructions:
• Universal commands — provide functions that are
implemented in all field devices, for example, read
manufacturer and device type, read primary variable
(PV), or read current output and percent of span
• Common practice commands — provide functions
that are common to many but not all field devices,
for example read multiple variables, set damping
time, or perform loop test
• Device-specific commands — provide functions
that are unique to a particular field device, for
example sensor trim. The 744 supports these
devices:
Today’s 744 supports device-specific instructions for a
variety of popular instruments. Additional support may
be added periodically with a simple software update
available on diskette or via download for a modest
upgrade fee.
HART operating modes supported
• For Point to Point operation, the most commonly
used mode, connects the 744 to a single HART
device in a 4-20 mA loop.
• In Multi-Drop mode, several HART instruments can
be bussed together. The 744 searches for each,
identifies addresses in use, and allows you to select
the instrument for calibration and related operations.
• In Burst Mode, the HART instrument transmits
bursts of data without waiting to be interrogated by
a master unit. The 744 can take transmitters out of
burst mode during test or calibration, then later
restore them to burst mode.
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
• Enhanced dry block delay setting for
temperature switch testing
• Switch test without reset
