Low cost calibrator muscle. 

For a powerful loop calibrator at a very affordable price, choose the new Fluke 705 Loop Calibrator. This feature-rich solution to loop calibration, maintenance and repair offers:

  • A large display and simple, pushbutton interface for ease of use.
  • Simultaneous mA and % readout for quick, easy interpretation of readings.
  • mA accuracy of 0.02%
  • Push button 25% steps for fast, easy linearity checks. Save time over traditional knob type controls.
  • "Span Check" for fast confirmation of zero and span.
  • Selectable slow ramp, fast ramp, and step to provide smooth outputs for valve slewing and loop functional tests.
  • 24 volt internal loop supply, so you can power and read a transmitter at the same time without carrying a DMM.
  • Single 9V battery that is easily changed.
  • 0 - 20 mA or 4 - 20 mA default start up modes.
