Calibration Drift definition

Calibration Drift means the change in the instrument meter readout over a stated period of time of normal continuous operation when the VOC concentration at the time of measurement is the same known upscale value.

Calibration Drift. (zero drift and span drift) means the value obtained by subtracting the known standard or reference value from the raw response of the continuous monitoring system.

Calibration Drift means the change in the instrument meter
