- Per apagar: Premeu i manteniu premut el botó d'engegada de nou fins que el dispositiu s'apagui.
4.3 Selecció de la llengua
Upon initial power-on or through the settings menu, you can select the display and voice prompt language between English and Chinese.
5. Instruccions de funcionament
5.1 Interfície de visualització
The 2.4-inch color LCD displays real-time gas concentrations for EX, H2S, CO, and O2. Units typically include PPM (Parts Per Million) for H2S and CO, %LEL (Lower Explosive Limit) for EX, and %VOL (Percentage by Volume) for O2. The display also shows battery status, time, and alarm indicators.
5.2 Navegació i configuració
Use the Up and Down buttons to navigate through menu options. Press the OK button to confirm selections or enter sub-menus. The Power button often doubles as a back or exit button in menu navigation.
Sistema d'alarma 5.3
The UT334 series features a quadruple alarm system to alert users to hazardous gas levels:
- Lights Flicker: Visual indication through flashing LEDs.
- Alarma del timbre: Audible alert sound.
- Red Background Reminder: The display background changes to red.
- Body Vibration: Tactile alert through device vibration.
The device allows for setting custom low and high alarm points for each gas. When gas concentrations exceed these preset thresholds, the quadruple alarm system activates.
