    HART Capabilities

    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.

    • 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.
    • Works with multiple masters, burst mode, and multi-drop configurations.
    • Is easy to update as additional instruments are added and new HART versions are released.
    • Interrogate to determine device type, manufacturer, model, tag.
    • Reconfigure the sensor mapping of dual sensor temperature transmitters.
    • 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 to the HART tag field.

    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.

    HART Operating Modes Supported

    • 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.

    Pressure Modules

    Covers virtually any pressure application including gauge, differential, dual (compound), absolute, and vacuum.

    • Display pressure readings in any of 10 different pressure units you specify in the calibrator setup.
    • Rugged urethane molded cases protect the modules from rough handling and harsh conditions.
    • Features internal temperature compensation from 0° to 50°C for full accuracy performance.
    • Includes NIST-traceable calibration certificate.
    • Modules can be calibrated locally, helping to control costs.

    A family of 29 optional pressure modules provides pressure calibration and measurement capabilities. Twenty-eight modules are available, with basic accuracy specs to 0.05%. Ranges start at 0 – 1 inH20 (0 – .25kPa) and go to 0 – 10,000 psi (0 – 70,000 kPa). Additional information about pressure modules is available on the Pressure Modules Home Page.

    Automated Procedures

    Allow you to quickly set up powerful, automated calibration procedures for linear transmitters, DP flow transmitters, and one- and two-point limit switches. Simply select the appropriate measure and/or source functions and fill out the procedure template. The 740 Series does the rest. It quickly performs the test, calculates the errors, and displays the final results, highlighting out of tolerance points.

    Custom Units

    Enable you to map one unit to another, such as mV to °C or °F. Allows you to use the Fluke 740 Series with millivolt output accessories such as the Fluke 80T-IR Temperature Probe, and to document tests using non-supported units such as parts per million or revolutions per minute.

    User-entered Values

    Enables technicians to record calibration results that were sourced and/or measured by other devices such as panel meters or readout-only devices.

    Limit Switch Calibration

    Procedures perform fast, automated calibration of one and two-point limit switches for voltage, current, temperature, and pressure.

    Differential Pressure Flow Instrument Calibration

    Routines use a square root function to directly calibrate DP flow instruments.
