5. Configuració
5.1 Instal·lació de la bateria
- Open the battery compartment cover on the back of the device using the provided screwdriver.
- Introduïu tres (3) piles AAA, assegurant-vos de la polaritat correcta (+/-).
- Tanqueu la tapa del compartiment de la bateria i fixeu-la amb el cargol.
5.2 Initial Power On and Preheating
- Press and hold the Power On/Off button (
) per encendre el dispositiu. - The LCD will display "ZERO WAIT...." and a countdown. Place the device in a clean air environment (free from gas) and wait for approximately 30 seconds for the sensor to preheat and stabilize. This ensures accurate readings.
- Once preheating is complete, the device is ready for use.
6. Instruccions de funcionament
6.1 Detecció de gasos
- After preheating, move the flexible gooseneck probe slowly towards the suspected area of a gas leak.
- Observe the LCD display and listen for the audible alarm.
6.2 Sensitivity Modes (LOW/HIGH)
The device offers two sensitivity modes:
- LOW Sensitivity: Use this mode to quickly identify the general area where a gas leak might be present. Press the 'LOW' button to activate.
- HIGH Sensitivity: Once a general area is identified, switch to 'HIGH' sensitivity by pressing the 'HIGH' button to pinpoint the exact source of the leak.

6.3 Audible and Visual Alarm
As the concentration of combustible gas increases, the device will provide dual alarms:
- Alarma visual: The analog bar on the LCD display will change color from blue to yellow, then to red, indicating increasing gas concentration.
- Alarma sonora: A beeping sound will become faster as the gas concentration rises. The alarm triggers when the concentration reaches 300 PPM.

6.4 Muting the Alarm Sound
Press the Alarm Sound On/Off button (
) to silence the beeping sound. Note that the device will still beep if the gas concentration exceeds 300 PPM, even if muted.
6.5 Temperature Units Selection
Press the °C/°F button (
) to switch the temperature display between Celsius and Fahrenheit.
6.6 Apagat automàtic
The device has a 10-minute automatic shutdown feature to conserve battery life. To toggle this feature on or off, briefly press the Power On/Off button (
) durant el funcionament.
7. Manteniment
