When you first create a probe scopePRO will experimentally
determine the fastest FFT algorithm to use. This process may take
up to 60 seconds to complete, at which point the software will
begin calculating velocity at the location.
3.
Click the + and
toolbar buttons to make the probes more or less
transparent. The software will continue to calculate velocity at
