CA51/CA71 Handy Calibrators

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 CA71 Handy Calibrator is a small, lightweight, multifunction calibrator that can simultaneously source and measure voltage, current, resistance, TC, RTD, frequency, and pulse signals. 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.

• 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 (TC and RTD measurement functions are CA71 only.)
• 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
• Online communication (CA71 only):
  RS-232C-compliant optically isolated interface
• 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
