Abstract
A measurement system including a plurality of self calibrating probes. Each probe has a sensor for providing a signal related to a physical parameter to be measured, and a connector for interfacing the sensor with a monitor. The connector includes a memory device for storing calibration data unique to the sensor. A cable interconnects the sensor with the connector. The monitor of the system includes a microprocessor for polling the storage device on the probe to extract the calibration data, and a software routine which converts the signal provided by the sensor into a calibrated signal and applies the extracted calibration data to the signal provided by the sensor.
