Yokogawa CA71 Multi-Function Portable Calibrator is a comprehensive measuring instrument for all your calibration and equipment checking needs at maintenance sites. The CA71 can instantaneously generate and calculate voltage, current, TC, RTD, and pulse signals; thus, you don’t need to prepare many instruments. For easy handling, the Convenient Calibrator integrates rotary switches. Only open the cover of the carrying case and connect the cables, and you’re ready to take measurements.
Features of Yokogawa Portable Calibrator:
- The CA71 helps you run routine testing on TCs, RTDs, and various other types of sensors and equipment, and where a problem has arisen, operation checks. It will produce input signals for equipment by itself and verify the output signal from the equipment.
- The CA71 can be used to monitor the input and output signals of each unit while concurrently testing the power supply in situations where various signal converters and other instruments are mounted on a rack or column. For calculating the supply voltage, there is no need for a separate multimeter.
- There is a divided output function (n / m), auto step function, sweep function, memory function, and contact function.
- For easy handling, the CA71 integrates rotary switches. Just open the carrying case cover and attach the
wires and the calculation are ready for you to take.
