CF-5200 Frequently Asked Questions

As a cause

(1) The rotation pulse signal is not being captured properly.
Please ensure that the current rotation display is shown accurately.

(2) Slow down the change in rotation.
At low speeds, the sampling frequency is low, which means data sampling takes a long time, and therefore the FFT process also takes a long time.
Furthermore, measuring the rotational speed takes time, delaying the determination of whether the rotational speed required for data collection has been reached.
Since the minimum measurable rotational speed is 20 r/min, it is possible that the rotational speed may fall below this minimum during the sample collection process.
