Optical Laser Mode
This extremely versatile mode allows the user to measure speeds of almost any machine or equipment where an exposed shaft is visible and on which a reflective marker can be attached. Ideal where engines cannot be accessed through the ignition system or Diesel injector pipework, the user simply needs to attach a small self adhesive reflective tape marker to the shaft which requires measurement, then measure from up to 2 meters away. An optional contact adapter is provided for applications where an end of shaft is accessible.
