4.2 Preparing the Target Surface

For accurate non-contact measurement, a reflective target must be applied to the rotating object. If the object's surface is already reflective, no additional target may be needed. Otherwise, attach a small piece of reflective tape (not included) to the rotating part where the laser beam will be directed.

5. Naudojimo instrukcijos

5.1 Įjungimas / išjungimas

Press the power button (usually located on the side or front) to turn the tachometer on. The LCD display will illuminate. Press and hold the power button again to turn the device off.

5.2 Selecting Measurement Mode (RPM / Total Revolutions)

The tachometer can measure either Revolutions Per Minute (RPM) or Total Revolutions. Press the 'RPM/TOT' button to toggle between these two modes. The selected mode will be indicated on the LCD display.

5.3 Matavimo atlikimas

  1. Ensure the tachometer is powered on and the desired measurement mode is selected.
  2. Point the laser beam at the reflective target on the rotating object. Maintain a detecting distance between 50mm and 500mm.
  3. Press and hold the measurement trigger button (often located on the side or front). The laser will activate, and the display will show the real-time measurement.
  4. Release the measurement trigger button to hold the last reading on the display.

5.4 Atminties funkcija

The tachometer automatically stores the last measurement, as well as the maximum and minimum measurements recorded during a measurement session.

  • Press the 'MEM' button to cycle through the stored values: Last Reading, Maximum Reading, and Minimum Reading.
  • To clear the memory, refer to the specific instructions in the device's full manual if available, or typically, turning the device off and on will clear the session memory.

6. Priežiūra

6.1 Valymas

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water. Keep the laser emission and reception lenses clean for accurate readings.
