Re-analysing (editing) records
Each record in a Size History can be edited and reanalysed, producing a new
result obtained using different measurement parameters.
For example, suppose the refractive index value used for the spray initially is
found to be incorrect. Select the record, edit the
Refractive Index parameter and
re-analyse the result to produce the correct values.
Records may need editing when any of the following change:
.
Optical properties.
.
Data alarm levels.
.
Analysis options.
Editing can be performed on one record in a PSD or a group of records from a
Size History. The method is different for each of these. (If the PSD is an average
result, it cannot be recalculated.)
'
N o t e
. Unless in 21 CFR Part 11 mode, when a backup is produced, the new
result replaces the previous record in the PSH file. We recommend
saving the file to be edited under a new name and performing the edit
on this file. This preserves the original record(s).
