Fluke 744 Documenting Process Calibrator-HART

Description

As more and more process plants begin to take advantage of smart transmitters, the need for a new generation of calibrators has emerged-calibrators that can communicate via industry standard digital protocols. The 744 combines HART communication capability to deliver an integrated communicating calibrator. This rugged, reliable tool is ideal for calibrating, maintaining, and troubleshooting HART and other instrumentation.

The 744 does the work of several tools - sourcing, simulating and measuring pressure, temperature, and electrical signals in one rugged, hand-held device.
For documentation, the 744 automates calibration procedures and captures your data. And, of course, it helps you meet rigorous standards like ISO 9000, FDA, EPA and OSHA regulations.

Features

  • Measure volts, mA, RTDs, thermocouples, frequency, and ohms to test sensors, transmitters and other instruments
  • Source/simulate volts, mA, thermocouples, RTDs, frequency, ohms, and pressure to calibrate transmitters
  • Power transmitters during test using loop supply with simultaneous mA measurement
  • Measure/source pressure using any of 29 Fluke 700Pxx Pressure Modules
  • Create and run automated as-found/as-left procedures to satisfy quality programs or regulations. Record and document results
  • Holds up to a full week of downloaded procedures and calibration results.
  • Use many features like autostep, custom units, user entered values during test, one-point and two-point switch testing, square root DP flow testing, programmable measurement delay etc.
  • Easy to use
  • Three year warranty
  • Bright white dual display. Read both sourced and measured parameters simultaneously.
  • Multi lingual interface
  • Rechargeable NiMH battery for 10 hour uninterrupted use. Includes gas gauge.
  • Handling of fast pulsed RTD transmitters and PLCs, with pulses as short as 1 ms.
  • Delivered with DPC/Track Sample software.
  • Compatible with many Asset Management software packages.

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.
