| Time-related analysis | The purpose of this page is to present several options for collecting data for estimating time-dependent effects in a measurement process. | ||
| Time intervals | The following levels of time-dependent errors are considered in
this section based
on the characteristics of many measurement systems and should be adapted to a
specific measurement situation as need be.
| ||
| Time intervals |
In all cases, data collection and analysis are straightforward, and there is no reason to estimate interaction terms when dealing with time-dependent errors. Two levels should be sufficient for characterizing most measurement systems. Three levels are recommended for measurement systems where sources of error are not well understood and have not previously been studied. | ||
