The Fluke Model 744 offers all the capabilities of the model 743B, plus
the ability to calibrate, maintain, and troubleshoot HART instrumentation.
Integrated HART communication functions permit you to monitor, control,
and calibrate HART instrumentation. It handles fast pulsed instruments,
RTD transmitters and PLC's, with pulses as short as 1ms.

- 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.
- 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 devise-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-to-day 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.
With the 744 DPC, you can:
Generate precision electrical, temperature, or pressure signals for analog
stimulus or sensor simulation.
Simultaneously measure electrical,
temperature, or pressure signals from transmitter output.
Determine type, manufacturer, model, tag
ID by interrogating HART devices.
Read HART PV function and smart
transmitter digital 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.
- Re-label smart transmitters by reading
and writing HART tag and message fields.
- Clone additional transmitters by
reading and storing basic HART configurations.
- Perform automated HART sensor trim and
output trim for selected devices in conjunction with As Found/As Left
tests.
- Perform loop test with simultaneous
analog and digital mA readout.
- Address new, fast, pulsed-excitation
smart transmitters and PLCs.
Instrumentation management software:
The Fluke 743B and 744 are compatible with Fluke 700SW DPC/TRACK
software and with software from Blue Mountain, Cornerstone,
Fisher-Rosemont, Honeywell, On Time Support and Prime Technologies.

The
standard specification intervals for the 744 is 1 and 2 years. Typical 90
day measurement and source accuracy can be estimated by dividing the one
year "% of reading" or "%of output" specifications by 2. Floor
specifications, expressed as "% of f.s." or "counts" or "ohms" remain
