5. Einrichtung
5.1 Einlegen der Batterie
- Unscrew the end cap of the device to access the battery compartment.
- Insert the two included AAA Alkaline batteries, ensuring correct polarity (+/-).
- Securely screw the end cap back onto the device.
5.2 Einschalten und Aufwärmen
- Halten Sie die Ein-/Aus-Taste (⏻) einige Sekunden lang, bis das Display aufleuchtet.
- The device will initiate a 30-second warm-up sequence, indicated by a countdown timer on the LCD screen. During this time, ensure the device is in a fresh air environment for accurate self-calibration.
- Once the warm-up is complete, the device will beep, and the display will show '0%LEL' or a stable low reading, indicating it is ready for use.
6. Bedienungsanleitung
6.1 Gaserkennung
- With the device powered on and warmed up, slowly move the sensor head near the area where a gas leak is suspected.
- Pay close attention to gas pipelines, connections, valves, and gas appliance areas (e.g., gas stoves, water heaters, furnaces, RV connections).

6.2 Alarmanzeigen
- Visueller Alarm: The bar graph on the LCD display will increase as the gas concentration rises. For high gas concentrations, the LCD screen will turn red.
- Hörbarer Alarm: A distinct beeping sound will accompany the visual alert. The frequency of the beep will increase with higher gas levels.
- %LEL Value: The display will show the real-time percentage of the Lower Explosive Limit (%LEL) for the detected gas.
6.3 Empfindlichkeitseinstellung
The PT205 features an 'S' button (Sensitivity) which allows you to adjust the detection sensitivity to suit different environments or specific detection needs. Refer to the detailed instructions in the included user manual for specific sensitivity level settings.
