Product Description
With DC voltage accuracy of ±0.02%, a built-in 24 V DC loop-power function and a vertical LCD layout, it replaces separate signal generators, decade resistors and multimeters in one tool. It is purpose-built for calibration and troubleshooting of transmitters, temperature controllers and signal converters at the maintenance site. The Yokogawa CA150 is a handy (portable) calibrator that simultaneously sources and measures voltage, current, resistance, thermocouple, RTD and pulse signals for field maintenance of process instruments.
