Hi Guys,
Got my new CM-140 today and laid it side by side with my RS 33-2055 Digital. Played a number of test tones (sine waves) from 30 Hz to 5000 hz and noticed that the SPL levels at different frequencies vary as much as 20 db! Could this be a bad meter? Which one? I'll try to chart them out this weekend and see what the difference is. Any thoughts or am I missing something.
