The MC4 is a documenting process calibrator for various process parameters, such as pressure, temperature and electrical signals. Instrument data can be sent from a computer to the calibrator, and calibration results can be uploaded from the calibrator to a computer using the company’s CMX calibration software. Using the calibrator together with the software provides a documenting calibration system that produces calibration certificates automatically. An accredited calibration certificate is included as standard with the calibrator as proof of the accuracy. The calibrator has a large graphical display, menu-based multilingual interface and full numerical keyboard.
