Sensors and instruments require a wide variety of operation checks in the field. The Yokogawa CA71 Handy CAL calibrator is a small, lightweight, multifunction calibrator that can simultaneously source and measure voltage, current, resistance, TC, RTD, frequency, and pulse signals. By itself, it can source signals for input to equipment and check output signal from equipment.

The Yokogawa CA71 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 includes divided output (n/m) to eliminate bothersome percentage calculations, auto step function that changes output value in step form based on divided output settings, sweep function that linearly increases or decreases output over 16 or 32 seconds, and memory function for 50 value sets.

In cases where numerous signal converters and other devices are mounted on a rack or panel, the CA71 can be used to check 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, as AC voltage measurement capability up to 300V is included.
