If extraHumid1 and outHumidity are not in that same loop packet then a correction expression will have no effect on the loop packet. If you are using hardware record generation then the correction will be applied to the archive record as well so that may do what you want for archive records. If you are using software record generation then no corrections are applied to archive records.
