• Brug ikke enheden, hvis den ser beskadiget ud.
• Ensure proper ventilation when investigating gas leaks.
• Hold enheden væk fra ekstreme temperaturer og fugt.
• Udskift batterierne med det samme, når indikatoren for lavt batteri vises.

3. Produktfunktioner

• Bredt registreringsområde: Detects gas concentrations from approximately 50 to 10,000 ppm (based on Methane).
• Justerbar følsomhed: Offers High (50 to 1000 ppm) and Low (1000 to 10,000 ppm) sensitivity levels.
• Enhanced Alerts: Features five red LEDs (visual) and an 85dB audible alarm that intensifies with increasing gas concentration.
• Automatisk kalibrering: Performs automatic zero-point calibration at power-up for accuracy.
• Fleksibel svanehals: An 18-inch flexible gooseneck expands the sensor's reach and clips onto the meter for storage.
• Holdbart design: Over-molded body provides a comfortable grip and is built for demanding environments.
• Batteribesparelse: Auto power-off after 10 minutes of non-usage conserves battery life.

4.2 Indledende kalibrering

The ET120 features automatic zero-point calibration. When the device is powered on, it will automatically calibrate itself to the ambient air. Ensure the device is powered on in an area known to be free of combustible gases for accurate calibration. Flashing lights will indicate the self-calibration process.

5. Betjeningsvejledning

5.1 Tænd/sluk

• To power on, press and hold the power button until the device activates.
• The device will perform an automatic self-calibration.
• To power off, press and hold the power button. The device also features an auto power-off function after 10 minutes of inactivity.

5.2 Justering af følsomhed

The ET120 offers two sensitivity modes:

• Høj følsomhed: Approximately 50 to 1000 ppm. Use for detecting smaller leaks or when precise location is needed.
• Lav følsomhed: Approximately 1000 to 10,000 ppm. Use for detecting larger leaks or initial scanning of an area.

Press the 'LOW' or 'HIGH' buttons on the device to switch between sensitivity modes.

5.3 Gasdetektionsproces

To detect gas leaks:

1. Sørg for, at enheden er tændt og kalibreret.
2. Extend the 18-inch flexible gooseneck to reach the area to be inspected. The gooseneck can be clipped onto the meter for convenient storage when not in use.
3. Slowly move the sensor tip of the gooseneck around potential leak sources.
4. Observe the five red LED indicators and listen for the audible alarm. The intensity of both the visual and audible alerts will increase as the gas concentration rises, indicating proximity to a leak.
5. Use the 'HOLD' button to freeze the current reading on the display if needed.

5.4 Mute-funktion

The audible alarm can be muted by pressing the speaker icon button. Press it again to unmute.

6. Vedligeholdelse

• Rensning: Wipe the device with a dry, lint-free cloth. Do not use abrasive cleaners or solvents.
• Opbevaring: Store the device in its carrying pouch in a cool, dry place away from direct sunlight and extreme temperatures.
• Batteripleje: Fjern batterierne, hvis enheden ikke skal bruges i længere tid, for at forhindre lækage.

7. Fejlfinding

• Enheden tænder ikke: Kontroller batteriinstallationen, og sørg for, at batterierne ikke er afladede. Udskift om nødvendigt.
• Unøjagtige aflæsninger: Ensure the device was calibrated in a clean, gas-free environment. Recalibrate if needed.
• No audible alarm: Check if the mute function is activated. Press the speaker icon button to unmute.
