5. Setup
5.1 Initial Charging
Before first use, fully charge the device using the provided charger and USB cable. Connect the USB cable to the detector's charging port and the charger to a power outlet. The battery indicator on the LCD screen will show charging status.
5.2 Powering On/Off
To power on the device, long-press the central Switch Key. The device will perform a self-check and warm-up, which typically takes 1-15 seconds. During this time, it may beep and vibrate. To power off, long-press the Switch Key again.
5.3 Warm-up Time
Allow the detector to complete its warm-up sequence (1-15 seconds) after powering on. This ensures the sensor is calibrated and ready for accurate detection.

6. Operation
6.1 Basic Gas Detection
Once the device has completed its warm-up, the LCD screen will display '0' (or a low background reading). Position the flexible gooseneck probe near the area suspected of a gas leak. Move the probe slowly to cover the entire area. The device will provide real-time readings on the LCD screen.
6.2 Sensitivity Levels
The detector features two sensitivity levels:
- Low Sensitivity: 500-2000ppm
- High Sensitivity: 2000-10000ppm
Refer to the manual for instructions on how to switch between sensitivity modes if needed. For general use, the default settings are often sufficient.
6.3 Alarm Indicators
When a gas leak is detected and the concentration exceeds the set alarm threshold, the device will activate its triple alarm system:
- Audible Alarm: A beeping sound will be emitted from the buzzer.
- Visual Alarm: The alarm indicator light will flash.
- Vibration Alarm: The device will vibrate.
The LCD screen will also display the detected gas concentration. The higher the concentration, the more frequent and intense the alarms.
6.4 Zeroing Function
The device supports both auto-zeroing and manual zeroing. Auto-zeroing occurs during startup. For manual zeroing, refer to the detailed instructions in the full user manual. This function helps ensure accurate readings by resetting the baseline in a clean air environment.

7. Maintenance
7.1 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the casing or internal components. Ensure the sensor area is kept clean and free from obstructions.
7.2 Battery Care
The device uses a 2000mAh rechargeable lithium battery. To prolong battery life, avoid fully discharging the battery frequently. Recharge the device when the low battery indicator appears. If storing the device for an extended period, charge it periodically to maintain battery health.
7.3 Sensor Lifespan
The imported sensor has a lifespan of up to 2 years. Regular use and proper maintenance can help maximize its operational life. If you suspect the sensor's accuracy has diminished, consider professional calibration or replacement.
8. Safety Information
This gas leak detector is a valuable tool for identifying potential gas leaks. However, it should not be used as a substitute for proper safety procedures or professional inspections. Always prioritize safety when dealing with combustible gases.
- Do not rely solely on this device for life safety. Install fixed gas detectors in appropriate locations.
- If a gas leak is detected, immediately ventilate the area, turn off gas sources if safe to do so, and evacuate. Contact emergency services or a qualified professional.
- Do not operate the device in extremely hazardous or explosive atmospheres unless specifically rated for such environments.
- Keep the device away from water and extreme temperatures.
- Ensure the device is fully charged before critical inspections to avoid interruptions.
