4. Operating Instructions

This non-contact tachometer measures RPM by detecting reflections from a target surface. For accurate readings, a reflective strip must be applied to the object being measured.

4.1 Preparing the Target Object

1. Ensure the surface of the object to be measured is clean and dry.
2. Cut a small piece of the provided reflective tape.
3. Firmly stick the reflective strip onto the rotating part of the object. Ensure it is flat and smooth.

4.2 Taking a Measurement

1. Hold the tachometer firmly.
2. Point the laser beam (emitted from the top front of the device) towards the reflective strip on the rotating object.
3. Press and hold the TEST button. The display will show the RPM reading.
4. Maintain a stable distance and aim for consistent readings.
5. Release the TEST button to stop measuring. The last reading will remain on the display.

4.3 Using the Memory Function

The tachometer includes a memory function to store and recall measurement data.

• Press the MEM button to cycle through stored values (e.g., maximum, minimum, last reading).
• Refer to the on-screen indicators for the type of memory displayed.

5. Maintenance

• Keep the device clean and dry. Use a soft, damp cloth for cleaning. Do not use abrasive cleaners or solvents.
• Avoid exposing the tachometer to extreme temperatures, humidity, or direct sunlight.
