When using REW with my RS digital SPL meter I also load the newrsdigital.cal correction file which I understand has correction values for 10 Hz up to 105 Hz. Do I also enable "compensate for c-weighting" in the REW program because whether I do or not affects measurements of frequencies from 105 Hz and higher. Again it had been noted before that the RS analog meter's RCA output is c-weighted compensated but there was never an exact consensus whether the RS digital meter's RCA output was c-weighted or unweighted. At the AVS forum, a poster claimed that it was unweighted but others begged to differ. Now that we have analog and digital meters that have been tested, what is the verdict with respect to the c-weighting output or not because, again, it does affect the frequencies above 105 Hz which the new calibration files do not compensate for.
