5. Подешавање и инсталација батерије

5.1 Инсталација батерије

Пронађите поклопац одељка за батерију на задњој страни уређаја.
Open the cover by sliding or unscrewing it.
Insert four 1.5V LR6 (AA) batteries, ensuring correct polarity (+/-).
Добро затворите поклопац одељка за батерије.

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. Упутство за употребу

6.1 Укључивање/искључивање

Притисните тастер 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 Р/Ц дугме за пребацивање.
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.
Напомена: 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

Притисните тастер Р/Ц 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)

Притисните тастер М/М/А button repeatedly to cycle through the following display modes:

МАКС: Displays the maximum measured value.
МИН: Displays the minimum measured value.
Просек: Displays the average measured value.
нормално: Displays the current real-time measurement.

6.5 Задржавање података

During measurement, a short press of the HOLD / ON/OFF button will freeze the current reading on the display. Press it again to release the data hold and resume live measurement.

6.6 СampПодешавање стопе линга

Тхе сampling rate can be adjusted from 0.5 to 255 seconds. Refer to the detailed user manual for specific steps on how to access and change this setting via the МЕНУ и ТУНЕ дугмад.
