5. Орнотуу жана Батареяны орнотуу
5.1 Батареяны орнотуу
- Аппараттын артындагы батарея бөлүкчөсүнүн капкагын табыңыз.
- Капкагын жылдырып же бурап ачуу менен ачыңыз.
- Insert four 1.5V LR6 (AA) batteries, ensuring correct polarity (+/-).
- Батарея уясынын капкагын бекем жабыңыз.
5.2 Applying Reflective Tape
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. Иштөө нускамалары
6.1 Күйгүзүү/өчүрүү
басыңыз 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 которуштуруу үчүн баскыч.
- 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.
- Эскертүү: 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).

6.3 Counts Measurement
- басыңыз R/C button to switch to Count measurement mode.
- Point the laser beam at the reflective tape on the object.
- The device will count the number of times the laser beam reflects off the tape.
6.4 Mode Selection (MAX/MIN/AVG)
