Sensors and instruments require a wide variety of operation checks in the field. The CA71 Handy Calibrator is a small, lightweight, multifunction calibrator that can simultaneously source and measure voltage, current, resistance, TC, RTD, frequency, and pulse signals. Simultaneous signal generation and measurement capability: The CA71 lets you handle regular tests on TCs, RTDs and various other types of sensors and instruments, as well as operation checks when a problem has occurred

Simultaneous signal source and measurement capabilities

The CA71 lets you handle regular tests on TCs, RTDs and various other types of sensors and instruments, as well as operation checks when a problem has occurred. By itself it can source signals for input to equipment, and check output signal from equipment. With the CA71, you don't need to worry about synchronizing operations with other setting devices. (TC and RTD measurement functions are CA71 only.)

AC Voltage measurement capablity (including supply voltage)

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. There is no need for a separate multimeter to measure supply voltage.

Easy operation

The Handy Calibrator incorporates rotary switches for simple handling. Just open the carrying case cover and connect the cables, and you're ready to take measurements.

A wide array of useful functions

  • Source:
    • Values set in steps of 4-20 mA24V DC Power Supply to Transmitter
  • Divided output (n/m) function
    • Output settings are divided, 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) function. Changes can be sourced automatically every 10% or 25%.
  • Online communication
    • RS-232C-compliant optically isolated interface
  • Sweep function
    • Linearly increases or decrease the output. The increasing/decreasing 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 read from the Handy Calibrator's internal memory (maximum 50 value sets).
  • Temperature monitor function
