View GuideWhy RMS velocity (ISO 10816) misses early bearing, gear, lubrication and cavitation faults — and how the high-frequency band, kurtosis and crest factor catch them weeks earlier.
View GuideMount, frame rate and duration decided before you press record — with a calculator that turns a shaft speed into camera settings, and tells you what the recording will and will not show.
