Building a Custom Drift Measurement

You can build a drift measurement using a WDM measurement you already

have as a reference. The selected channels and thresholds can be

imported from the analysis setup or the reference measurement.

A custom drift measurement is particularly useful for offline processing of

your data over time and comparing result variations.

The WDM measurements you add must meet specific criteria to be

included in the custom build. The table below describes those

compatibility criteria.

Note: Files that are not compatible will automatically be rejected from the custom

build measurement.
