Reflective mark
Cut the adhesive tape into squares of approximately 12mm (0.5") and apply one square to
each rotation shaft.
a. The non-reflective area must always be greater than the reflective area.
b. If the shaft is normally reflective, it must be covered with black tape or black paint before
attaching reflective tape.
c. Shaft surface must be clean and smooth before applying reflective tape.
Very Low RPM Measurement
To improve repeatability of low RPM measurements, it is recommended to apply additional
squares of reflective tape. Divide the reading shown on the display by the number of pieces
of reflective tape squares to calculate the actual RPM.
