Description

Sensors and instruments require a wide variety of operation checks in the field. The Yokgawa 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 CA71 is a comprehensive generating / measuring instrument for all your calibration and equipment checking needs at maintenance and production sites, making your task much easier. In addition, The CA71 incorporates a rotary switches for simple handling. Just open the carrying case cover and connect the cables, and you’re ready to take measurements

IIII [+] Read More

The CA71 lets you handle regular tests on TCs, RTDs and various other types of sensors and instruments, as well as operation checks for preventative maintenance. By itself it can source signals for input to equipment, and check output signal from equipment. You don’t need to worry about synchronizing operations with other setting devices.

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.
