Spectral Equalizer
Selecting this option evenly distributes the power across the frequency
spectrum to provide more equal weighting at every frequency. This often
is a very effective tool for improving correlations.
Peak Enhancer
Selecting this option can enhance the peak values on the graph. Use this
feature only for plastic pipes.
Center Correlation Suppression
Selecting this option removes the center of the correlation from the
calculations to minimize errors caused by common noise signals providing
an artificial correlation at zero time delay. Set the width of the suppression
in milliseconds (ms) as required.
Sound
This tab displays the detected noise signals for the red, blue, or yellow
transducers as waveforms. Throughout a correlation, the waveforms
represent the sound as it is undergoing analysis.
