5. Setup
5.1 Battery Installation
The ANENG GN807 requires three (3) 1.5V AAA batteries (not included). Follow these steps to install the batteries:
- Use a screwdriver to unscrew the battery cover located on the back of the device.
- Load three 1.5V AAA batteries, ensuring correct polarity (positive and negative electrodes) as indicated inside the compartment.
- Replace the battery cover and secure it with the screws.
If the battery symbol appears on the screen, it indicates that the battery needs to be replaced.
6. Operation
6.1 Power On and Warm-up
- Power On: In a clean air environment, press the power button (7) to turn on the device.
- Warm-up: The meter will preheat for approximately 30 seconds. During this time, the screen simulation section will rise and beep. Wait until the preheating is complete before proceeding with detection.
6.2 Gas Leak Detection
The ANENG GN807 can detect various combustible gases, including Methane, Acetone, Acetylene, Alcohol, Ammonia, Benzene, Butane, Ethanol, Ethylene Oxide, Gasoline, Ethane, Hydrogen, Naphtha, Paint Thinner, and Propane.
- Positioning the Sensor: After warm-up, take the detector to the detection environment. Use the flexible gooseneck (2) to bring the sensor (1) close to the suspected leak point.
- Interpreting Readings:
- If no combustible gas is detected, the analog section of the display screen will not rise, and there will be no beep.
- When combustible gas is detected, the simulated segments on the screen will rise, and the device will emit a sharp buzzer alarm. The gas concentration is displayed in PPM.
- Buzzer Control: Press the buzzer switch (6) to turn the audible alarm on or off as needed.
6.3 Sensitivity Adjustment
The device offers two sensitivity levels:
- Low Sensitivity (SENS-L): Press the "LOW" button (4) for less sensitive detection.
- High Sensitivity (SENS-H): Press the "HIGH" button (5) for more sensitive detection.
6.4 Temperature Unit Selection
Press the °C/°F button (8) to switch between Celsius and Fahrenheit temperature units on the display.
6.5 Automatic Shutdown
The device is equipped with an automatic shutdown feature. If there is no operation for 10 minutes, the meter will automatically shut down to save battery life. To cancel this feature in the power-on state, press the power button (7).
7. Maintenance
7.1 Battery Replacement
Refer to Section 5.1 for detailed instructions on battery installation and replacement. Always replace all three AAA batteries at the same time with new ones to ensure optimal performance.
7.2 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the casing or display. Keep the sensor tip clean and free from debris.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Dead or incorrectly installed batteries. | Check battery polarity and replace with fresh AAA batteries. |
| No alarm when gas is present | Buzzer is turned off; low sensitivity setting; sensor obstruction. | Ensure buzzer is on (press button 6); switch to High sensitivity (button 5); clean sensor tip. |
| Inaccurate readings | Sensor contamination; device not warmed up; incorrect sensitivity. | Clean sensor tip; allow full warm-up (30 seconds); adjust sensitivity as needed. |
| Automatic shutdown occurs unexpectedly | Automatic shutdown feature is active and no operation for 10 minutes. | This is normal behavior. To disable, press the power button (7) after powering on. |
9. User Tips
- Pre-test in Fresh Air: Always power on the device in a clean, gas-free environment to allow for proper warm-up and calibration.
- Utilize Gooseneck: The flexible gooseneck is designed for hard-to-reach areas. Bend it carefully to access tight spots without straining the device.
- Adjust Sensitivity: For general checks, Low sensitivity might suffice. For pinpointing small leaks or in less concentrated areas, switch to High sensitivity.
- Monitor Battery Life: Pay attention to the low power prompt on the display and replace batteries promptly to avoid interruptions during critical detection tasks.
