Comprehensive source/measure instruments for all your calibration and equipment checking needs at maintenance sites Sensors and instruments require a wide variety of operation checks in the field. The 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 CA51 Handy Calibrator is a basic model with the same functions as the CA71 except TC and RTD measurement functions and online communication functions. Simultaneous signal source and measurement capability The...
