5. Návod k obsluze
5.1 Zapnutí/vypnutí
- Stiskněte tlačítko Tlačítko napájení (
) pro zapnutí zařízení. - Stiskněte a podržte Tlačítko napájení for a few seconds to turn the device OFF.
5.2 Nastavení nuly
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.
- Stiskněte a podržte DRŽET tlačítko po dobu přibližně 5 sekund.
- The display will show "----" indicating that the zero setting is complete.

5.3 Výběr jednotky
Stiskněte tlačítko JEDNOTKA 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 Funkce podsvícení
Stiskněte tlačítko Tlačítko podsvícení () to turn the LCD backlight ON or OFF for improved visibility in low-light conditions.
5.5 Zadržení dat
Stiskněte tlačítko DRŽET 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
Stiskněte tlačítko REC button to enter recording mode. In this mode, the device will track the maximum, minimum, and average pressure values. Press REC repeatedly to cycle through MAX, MIN, AVG, and DIF displays. To exit recording mode, press and hold the REC tlačítko.
5.7 Automatické vypnutí
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.
