Yokogawa CA450-E/TE - Loop Calibrator/Digital Multimeter


The Yokogawa CA450 is a meter which integrates the functionality of a loop calibrator with that of a digital multimeter, combining 2 units into 1! From daily inspection to the troubleshooting of measurement instruments, this meter does it all!

The CA450 is loop-powered and has a 4-20 DCmA output to go along with the standard multimeter functions like measuring voltage, current, frequency and continuity. And by utilizing the IR-USB communication function, you can send measured values to a PC, or transfer settings for measurement of generated current from the PC to the main unit.


  • Simultaneous 24V loop power and mA measurement
  • HART mode setting with loop power (250 Ohm resistance)
  • SIMULATE function simulates transmitters
  • 4-20 DCmA Span/Step/Auto-Step/Sweep Output
  • Handheld DMM functions with high accuracy measurements
  • Peak/Hold function for DCS power peak-to-peak measurement
  • Dedicated sensor modes for direct reading of many sensor signal types
  • Current terminal shutter prevents incorrect connections
  • Transfer data to a PC via IR-USB communication function
  • Meets CAT III 1000V and CAT IV 600V safety standards
