Overview
The Yokogawa CA71 Calibrator is a small, lightweight, multifunction calibrator that can simultaneously source and measure voltage, current, resistance, Thermocouples, RTDs, frequency, and pulse signals. With simultaneous signal generation and measurement capabilities, the CA71 lets you handle regular tests on Thermocouples, RTDs and various other types of sensors and instruments, as well as operation checks when a problem has occurred. This handy calibrator also incorporates rotary switches for simple handling. Just open the carrying case and connect the cables, and you're ready to take measurements.Features
