In DI.Screening Analysis, the type of evaluation mode can be selected between Spectral Shift or TRIC measurements on the data page of the software. Spectral Shift are always measured and is the default for the DI.Screening Analysis. If the data was measured with 5 sec on-time, the analysis could still be done at 1.5 sec, 3 sec on-time or 5 sec on-time.
