Dynamic Capability too lowThis warning is issued if a band has a measured F2 > Ld.
This may be avoided by proper calibration, and avoiding measuring a highly reactive sound field. Try to move away from the source or eliminate extranous noise sources to avoid the warning.
The yellow warning is issued for a segment. The measurement is still compliant to the standard if the summed bands in total scope fullfills the requirement. Otherwise, a red warning will be issued.
