5-2 VERY LOW RPM MEASUREMENT
"As it is easy to get high resolution and fast sampling time. If measuring the very low RPM values, suggestuser to attach more "REFLECTIVE MARKS" averagely. Then divide the reading shown by the number of "REFLECTIVE MARKS" averagely. Then divide the reading shown by the number of "REFLECTIVE MARKS" to get the real RPM".
This product was made in China, btw.
