    The 743B is easy to use with flexible test strategies. And like all Fluke tools, it's rugged, reliable and tough as nails. It's like having several powerful tools in one - so you can work faster than ever:
    • 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
    • Measure and source with one compact, rugged, reliable tool
    • Create and run automated as-found/as-left procedures to satisfy quality programs or regulations. Record and document 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 display. Read both sourced and measured parameters.
    • Multi lingual interface
    • Handling of fast pulsed RTD transmitters and PLCs, with pulses as short as 1msec.
    • Standard delivered with DPC/Track Sample software. Compatible with many Asset Management software packages.

For the calibration and troubleshooting of process control instrumentation.

We know how tough your job can be. You've got a lot to deliver in as little time as possible. So we've made it easier on you - with our multifunction 740B Series Documenting Process Calibrators.

The 740 Series does the work of several tools - sourcing or measuring pressure, temperature, and electrical signals in one rugged, hand-held device.

For documentation, the 740 Series automates calibration procedures and captures your data - for easy transfer to a PC using Fluke DPC/Track software or other popular packages. And, of course, it helps you meet rigorous standards like ISO 9000, FDA, EPA and OSHA regulations.

The 740 Series is easy to use with flexible test strategies, user-entered values, custom units, even a built in calculator. And like all Fluke tools, it's rugged, reliable and tough as nails. It's like having several powerful tools in one - so you can work faster than ever:

  • Calibrate temperature, pressure, voltage, current, resistance, and frequency.
  • Measure and source with one compact, rugged, reliable tool.
  • Create and run automated as-found/as-left procedures to satisfy quality programs or regulations. Supports linear, square-root devices plus one-point and two-point limit switches.
  • Record and document results.
  • Transfer the results to a PC (743B and 744 only), saving the time to manually transcribe data. Run popular instrumentation management software.
  • HART communication capability lets you program and control HART instrumentation (744 only).
What's included:
  • TL224 Industrial Test Leads (2 sets)
  • AC220 Test Clips (2 sets)
  • TP220 Test Probes
  • BP7217 Battery Pack
  • BC7217 Battery Charger
  • Instruction manual
  • NIST Traceable calibration certificate and data
  • Three year warranty
  • serial port cable (743B and 744 only)
  • DPC/TRACK Sample Version with free PC communication utility software (743B and 744 only).

The Fluke 741B offers simultaneous source and measure capabilities for all common process parameters. Create and execute automated procedures and automatically capture the results.

The Fluke 743B offers all the capability of the 741B, plus adds a serial interface for two-way communication applications.

The Fluke 744 offers all of the capabilities of the 743B, plus the ability to maintain and calibrate selected HART transmitters without a second tool.

90 day specifications

The standard specification intervals for the 743B 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 full scale" or

"counts" or "ohms" remain constant.
