The CC550 is a part of Testec's extensive line of calibration and testing equipment. It is an automated calibration device used to accurately calibrate pressure, temperature, and voltage sensors. The device is fitted in a rugged aluminum case and has a housing plate with a top and bottom plate and two reference standard ports. The CC550 provides three modes of operation: calibration, comparison, and meter verification. The calibration mode holds two digital references to accurately calibrate and adjusts pressure, voltage, and temperature sensors. The comparison mode allows for the accurate comparison of two pressure, voltage, and temperature sensors. The meter verification mode allows for the accurate measurement of voltage, current, and resistance of analog and digital circuit components. This device also has numerous built-in features such as an RS-232 interface, power failure feature, adjustable scan time and scan interval, a time-stamped output for traceability, industrial rate accuracy, on-board memory for data storage, and a power indicator.
