I've read through the REW help file 3 times now. It never mentions in the setup and calibration process on when to load the SPL meter correction file.

When should the SPL Meter correction file be loaded? Before Checking Levels? Before SPL Calibration procedure? Before Making measurements??

Load the SPL meter calibration file after you've finished creating the soundcard calibration file and checking the soundcard calibration file with the loopback cable. Remove the loopback cable, hook up the SPL meter and the cable to your receiver, then load the SPL meter file....
