5.3 Dujų aptikimo procesas

To detect gas leaks:

1. Įsitikinkite, kad įrenginys įjungtas ir sukalibruotas.
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.
