5. Упутство за употребу
5.1 Укључивање/искључивање
- Притисните тастер Дугме за напајање (
) to turn the device ON. - Притисните и држите Дугме за напајање for a few seconds to turn the device OFF.
5.2 Подешавање нуле
Before taking any measurements, it is crucial to perform a zero setting to ensure accuracy. Disconnect all pressure hoses from the device before performing this step.
- Ensure the device is powered on and no pressure is applied to the ports.
- Притисните и држите ХОЛД дугме око 5 секунде.
- The display will show "----" indicating that the zero setting is complete.

5.3 Избор јединице
Притисните тастер УНИТ button to cycle through the 11 available pressure units (Psi, kPa, Kgfcm2, ozin2, Bar, mbar, inHg, mmHg, inH2O, ftH2O, cmH2O) until your desired unit is displayed.
5.4 Функција позадинског осветљења
Притисните тастер Дугме за позадинско осветљење () to turn the LCD backlight ON or OFF for improved visibility in low-light conditions.
5.5 Задржавање података
Притисните тастер ХОЛД button briefly to freeze the current reading on the display. Press it again to release the hold function and resume live readings.
5.6 MAX/MIN/AVG/DIF Recording
Притисните тастер РЕЦ button to enter recording mode. In this mode, the device will track the maximum, minimum, and average pressure values. Press РЕЦ repeatedly to cycle through MAX, MIN, AVG, and DIF displays. To exit recording mode, press and hold the РЕЦ дугме.
5.7 Аутоматско искључивање
The device will automatically power off after 25 minutes of inactivity to save battery life. This feature can typically be disabled or adjusted by pressing and holding specific buttons during power-on, as detailed in the full manual.
