Fluke 754: The HART calibrator that is easy to use.
HART applications
Versatile HART protocol support
The 754 supports the commands contained in HART protocol version 5.7.
The 754 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 754 supports these
devices:
Today’s 754 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, con-
nects the 754 to a single HART
device in a 4-20 mA loop.
• In Multi-Drop mode, several
HART instruments can be bussed
together. The 754 searches for
each, identifies addresses in
use, and allows you to select the
instrument for calibration and
related operations.
• In Burst Mode, the HART instru-
ment transmits bursts of data
without waiting to be interro-
gated by a master unit. The 754
can take transmitters out of burst
mode during test or calibration,
then later restore them to burst
mode.

- Allowance for traceability fluke specs are not relative specs but total specs 9
- C compensation factors are provided to permit specified use of the calibra tors over a wide 10 c to 50 c range 9
- Confidence interval k 3 9
- For example fluke specifications use a 3 sigma confidence interval k 3 this means that 99 of measurements will remain in specification over the stated period of time other manufacturers use a 2 sigma confidence interval k 2 this means that 95 of measurements will remain in specification over the stated period of time so one in 20 instruments are statistically likely to fail to perform to their specifications 9
