These compact, robust, easy-to-handle calibrators have large LCD screens and are suitable for use in highly diverse on-site conditions. They can calibrate an instrument in its operating environment and without removing it from the process. The principal functions are simulation and measurement. They simulate a signal or generate a quantity with precisely-defined values, for applying upstream of the measurement chain, and measure the signal. The CA1621, CA1623 & CA1631 calibrators are designed to accurately measure, generate or simulate all the low-level signals encountered in industry. Applications include maintenance operations, commissioning, verification, on-line calibration and adjustment and testing of measurement lines.
