Document Summary
The test instrument or sensor is then modified so that its output equals the output of the instrument or sensor with known accuracy. This is done to unsure the accuracy of all instruments or sensors within a measurement range. A calibration chain is the hierarchy or mapping of accuracy/calibration ratings for a given device or devices. Traceability is the ability to find and verify a given device"s location, usage, or history by utilization of a. A standards laboratory is a place in which individual devices can be calibrated to match the accuracy devices of higher standards that is higher on the calibration chain. The calibration procedure should be managed by providing a calibration environment in which proper temperature, humidity, high standards of cleanliness, and good housekeeping should all be provided. Also, reference instruments used for calibrating must be maintained to reference standards and supported by calibration certifications that establish its traceability.
