5.1 Hidupkan/Mati Kuasa

• 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 Melaraskan Kepekaan

The ET120 offers two sensitivity modes:

• Sensitiviti Tinggi: Approximately 50 to 1000 ppm. Use for detecting smaller leaks or when precise location is needed.
• Sensitiviti Rendah: 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 Proses Pengesanan Gas

To detect gas leaks:

1. Ensure the device is powered on and calibrated.
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.
