Product Overview

RENT FLUKE 744 DOCUMENTING PROCESS CALIBRATOR (Call for Availability)

The Fluke 744 Documenting Process Calibrator is a rugged hand-held device that does the work of several tools including sourcing, simulating and measuring pressure, temperature, and electrical signals. This powerful and reliable multifunction documenting calibrator lets you download procedures, lists and instructions and upload data for printing, archiving, and analysis. The powerful built-in HART® interface makes the Fluke 744 ideal for calibrating, maintaining, and troubleshooting HART and other instrumentation.

Features and Specifications of the Fluke 744 Documenting Process Calibrator include:

Features of the Fluke 744 Calibrator:

  • Automated procedures: 
    • Allows quick set up of powerful, automated calibration procedures for linear transmitters, DP flow transmitters, and limit switches:
      • Handling of fast pulsed RTD transmitters and PLCs, with pulses as short as 1 ms
      • DP flow instrument calibration: Routines use a square root function to directly calibrate DP flow instruments
      • Limit switch calibration: Procedures perform fast, automated calibration of one-point and two-point limit switches for voltage, current, temperature, and pressure
  • Custom units enable user to map one unit to another
  • User-entered values enables the recording of calibration results that were sourced and/or measured by other devices such as panel meters or readout-only devices
  • Multifunctional:  
    • Calibrate temperature, pressure, voltage, current, resistance, and frequency
    • Three operating modes: Measure, Source, or simultaneous Measure/Source allows user to troubleshoot, calibrate, or maintain instrumentation with just one rugged tool 
  • Powerful, yet easy to use:
    • Easy-to-follow menu-driven display that guides user through any task
    • Programmable calibration routines that allow creation and running of automated as-found/as-left procedures to ensure fast, consistent, calibrations
  • Records and documents results:
    • Captures calibration results
    • RS-232 interface allows transfer of results to a PC 
  • Bright white dual display:
    • Read results in any light
    • Read both sourced and measured  parameters simultaneously
  • Soft keys provide one-touch access to enhanced functions
  • Hand-held, small enough to fit easily into a tool bag, and to use in tight spaces
  • Rechargeable NiMH battery for 10 hours of uninterrupted use
  • Rugged and reliable: Overmolded uerthane case stands up to rough handling in industrial environments
  • Built-in algebraic calculator:
    • Has four functions, plus square root, stores, recalls, and performs calculations required for setting up instruments or evaluating data in the field 
    • Can use it to set the source function to a calculated value
  • Programmable measurement delay: Inside automated procedures permits calibrating instruments that respond slowly 
  • Powerful built-in HART interface that offers the communication capabilies of the 275 HART communicator
