Characteristics:

  • AC voltage (including supply voltage) measurement capability:
    In cases where numerous signal converters and other devices are mounted on a rack or panel, the Handy Calibrator can be used to check the input and output signals of each device, while simultaneously checking the power supply.
  • A wide array of useful functions
  • Source:
    Values set in steps of 4-20 mA, 24V DC Power supply to transmitter
  • Divided output (n/m) function:
    Output settings are divided (n/m), eliminating the need for bothersome calculations for percentage output
  • Auto step function:
    Changes the output value in step form based on the setting from the divided output (n/m) functions. Changes can be generated automatically every 10% or 25%
  • Sweep functions: Linearly raises or lowers the output. The raising/lowering time can be set to either 16 or 32 seconds
  • Memory function:
    Source values and measurements forming individual value sets can be saved to or loaded from the Handy Calibrator’s internal memory (maximum 50 value sets)
  • Easy operation:
    The Handy Calibrator incorporates rotary switches for simple handing. Just open the carrying case cover and connect the cables, and you’re ready to take measurements

Product Description:

space
Comprehensive source/measure instruments for all your calibration and equipment checking needs at maintenance sites. Sensors and instruments require a wide variety of operation checks in the field. The CA51 Handy Calibrator is a basic model with the same functions as the CA71 except TC and RTD measurement functions and online communication functions.
