If the frequency response of your transducer (or sensor) is not as flat as you want, a correction table can be
added while entering the data for the input device.
The table has 1/3rd octave frequency resolution, and is stored together with the transducer. A copy
of this transducer data will also be stored together with each measurement result. It can therefore be turned on and
off after the measurement is finished. This is typically done in postprocessing software.
