5.1 Agbara Tan / Pa
- Press and hold the Power Button to turn the device ON or OFF.
- Upon powering on, the device will undergo a warm-up period of approximately 30 seconds. The display will show "WAIT..." during this time.
5.2 odo odiwọn
- For TA8408A, the device performs auto zero calibration.
- For TA8408B/C, the device performs auto zero calibration upon startup. You can also perform manual zero calibration by pressing the "ZERO" button in a clean air environment.
5.3 Atunse ifamọ
- Press the "SENS" button to cycle through sensitivity levels: Low (Lo), Medium (Mid), and High (Hi).
- Higher sensitivity is suitable for detecting small leaks, while lower sensitivity helps to pinpoint larger leaks or avoid false alarms in environments with trace gases.
5.4 gaasi erin
- Ensure the device has completed its warm-up and zero calibration.
- Slowly move the sensor (goose neck tip) towards the suspected leak area.
- Observe the display and listen for the alarm. The response time is less than 2 seconds.
- The device will emit a sound and light alarm when gas is detected. The intensity of the alarm and the display reading will increase with higher gas concentration.
5.5 Display Interpretation (TA8408B/C)
The TA8408B/C models feature a digital analog bar display with specific alarm thresholds:
- SENS-H: High sensitivity, alarm when concentration is ≥ 1.00% LEL (500 PPM).
- SENS-L: Low sensitivity, alarm when concentration is ≥ 10.00% LEL (5000 PPM).
- %LEL: Lower Explosive Limit percentage.
- PPM: Parts Per Million, indicating a few percent of the leakage.
5.6 Unit Switching (TA8408B/C)
- Press the "PPM/%LEL" button to switch between Parts Per Million (PPM) and Lower Explosive Limit (%LEL) units for gas concentration display.
- Press the "C/F" button to switch between Celsius (℃) and Fahrenheit (℉) for ambient temperature display.
5.7 Alarm Sound On/Off (TA8408B/C)
- Press the Speaker Icon button to toggle the audible alarm sound on or off. The visual alarm will remain active regardless of the sound setting.

- No gas detection or inconsistent readings:
- Ensure the sensor tip is clean and unobstructed.
- Verify the device has completed its warm-up period.
- Perform zero calibration in a clean air environment.
- Adjust sensitivity to a higher level if detecting small leaks.
- Ensure the device is used within its specified operating environment.
- Alarm sounds continuously in clean air: Perform zero calibration in a fresh air environment.

9. Awọn imọran olumulo
- Always perform a zero calibration in a fresh air environment before starting your detection work to ensure accurate readings.
- When searching for small leaks, use the high sensitivity setting and move the probe slowly to allow the sensor enough time to react.
- For pinpointing the exact source of a leak, start with high sensitivity to detect the general area, then switch to lower sensitivity to narrow down the location.
- Keep the sensor tip clean to prevent false readings or reduced sensitivity.
- Be aware of the auto-off function to conserve battery life.
