Refl ective mark: cut and peel adhesive tape provided into approx. 12mm (0.5") squares and
apply one square to each rotation shaft. The non-refl ective area must always be greater than the
refl ective area. If the shaft is normally refl ective, it must be covered with black tape or black
paint before attaching refl ective tape. Shaft surface must be clean and smooth before applying
refl ective tape.
2
Very low RPM measurement: as if is easy to get high resolution. If measuring the very low
RPM values, suggest user to attach more "refl ective marks" averagely. Then divide the reading
shown by the number of "refl ective marks" to get the real RPM.
3
Contact tachometer parts include large taper, small taper and pillar, large taper and pillar rubber
part is suitable to low speed and but the small high speed.
