For accurate non-contact measurement, apply a piece of reflective tape to the rotating object whose speed or count you wish to measure. Ensure the tape is clean and securely attached.
6. Instruccions de funcionament
6.1 Encès/Apagat
Premeu el botó HOLD / ON/OFF button to turn the tachometer on or off.
6.2 RPM Measurement
- Ensure the device is in RPM measurement mode (indicated on the LCD). If not, press the R/C botó per canviar.
- Point the laser beam at the reflective tape on the rotating object.
- Maintain a measurement distance between 50mm and 200mm (2 to 8 inches) from the target.
- The RPM reading will be displayed on the LCD.
- Nota: If no signal is detected within 7 seconds, the LCD will display "0.0000". If the RPM exceeds 99999, the LCD will display "OL" (Overload).
