Fluke 789 Loop Calibrator Processmeter

Fluke Model 789 Process Meter & Calibrator
        
  

      Fluke combined a loop calibrator and a DMM to give process technicians double the power in one tool (the Fluke 787).  Now we made it even better - the ultimate loop calibration multimeter - the Fluke 789 ProcessMeter. The 789 has a display that's not only twice as large, but also twice as bright with two levels of backlighting. With its built-in, selectable 250 ohm HART® resistor, it eliminates the need to carry a separate resistor with you.  Now process technicians can do a lot more while carrying a lot less.

Features:

  • DMM and Loop Calibrator with 
  • 24 V Loop power supply 
  • HART mode setting with loop power (adds 250 ohm resistor) 
  • 100 % larger dual display 
  • 1,200 ohm drive capability on mA source 
  • Enhanced backlight with two brightness settings 
  • 0-100 % mA Span Check buttons to toggle between 4 and 20 mA 
  • Infrared I/O port for use with FlukeView Forms Software  
  • Externally accessible fuses for easy replacement 
  • DMM designed to meet 1000 volt IEC 1010 CAT III standards 
  • Precision 1000 V, 440 mA true-rms digital multimeter 
  • Frequency measurement to 20 kHz 
  • Min/Max/Average/Hold/Relative modes 
  • Diode Test and Continuity Beeper 
  • Simultaneous mA and % of scale readout 
  • 20 mA dc current source/loop calibrator/simulator 
  • Manual Step (100 %, 25 %, Coarse, Fine) plus Auto Step and Auto Ramp 
  • Externally accessible battery for easy battery changes 
  • IR communication port allows data to be logged to optional 
  • FlukeView Forms Software  for graphical analysis and reporting
