4.3.1 RPM Measurement
Reflective
tape
• Apply a reflective mark or a piece of reflective tape to the
rotating object under measurement.
• Press the "Measurement trigger" and verify that the "RPM
Indicator" is shown in the display. If the RPM function is not
selected, press the "RPM/COUNT button" once to select the
RPM function.
• Press the "Measurement trigger" and aim the laser beam at the
reflective mark or tape on the rotating object.
