4.3 Measurement Procedures
! CAUTION: Avoid contact with moving and/or
hot components, to prevent personal
injury or damage to the instrument.
! CAUTION: Laser radiation is emitted
Avoid direct eye contact
4.3.1 RPM Measurement
• 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.
• Verify that the “On Target indicator” appears on the display,
indicating that the instrument is detecting the rotation of the
object and the reflective mark on it.
• Proceed to read the RPM on the digital display.
