Calibrator Drift - How to Incorporate it into uncertainty calculations in Met/Cal?
I don't know if this has been discussed previously, but I would like to know how to incorporate calibrator drift for uncertainty calculations into a Met/Cal procedure. (Calibrator: reference or standard; it can be a calibrator or reference multimeter. Drift: the change in specification over time)
The 5522A specifications reads under Absolute Uncertainty Definition as follows "The 5522A specifications include stability, temperature coefficient,linearity, line and load regulation, and the traceability of the external standards used for calibration."
Does "stability" means drift? If it doesn't, then how do I incorporate drift in the uncertainty calculations? Can it be added yearly to the calibrator's accuracy file and if so, how?
