Re fl ective mark: cut and peel adhesive tape provided into approx. 12mm (0.5”) squares and

re fl ective area. If the shaft is normally re fl ective, it must be covered with black tape or black
paint before attaching re fl ective tape. Shaft surface must be clean and smooth before applying
re fl ective tape.
Very low RPM measurement: as if is easy to get high resolution. If measuring the very low
RPM values, suggest user to attach more “re fl ective marks” averagely. Then divide the reading
shown by the number of “re fl ective marks” to get the real RPM.
