The FT-7200 can measure the rotational engine speed by the sound and vibration related to the movement of the pitons. It is effective to measure when the engine rotational sensor cannot be attached because the engine compartment is covered. By setting the number of ignition firings per one crankshaft rotation, it can be measured rotational speed to perform frequency analysis through FFT calculation. (ex. Set at 2 P/R in a four-cylinder engine with four-cycle)

Analog output and sensor signal monitor output are provided as standard. Analog output can be used as recording the fluctuation of rotational speed to data recorder and so on, and sensor signal monitor output can be used in order to check the shape of signal waveform.
