4.1 Pemasangan Bateri

The ANENG GN805 requires two 1.5V AAA batteries (not included). Follow these steps for proper installation:

Figure 3: Step-by-step guide for installing two AAA batteries into the ANENG GN805.

1. Buka Penutup Bateri: Use a screwdriver to unscrew the battery cover located on the back of the device.
2. Muatkan Bateri: Insert two 1.5V AAA batteries, ensuring correct polarity. The springs at both ends are designed to protect the battery.
3. Tutup Penutup Bateri: Gantikan penutup bateri dan kencangkannya dengan skru.

A low power prompt will appear on the LCD display when the batteries need replacement.

5. Arahan Operasi

5.1 Hidupkan/Mati Kuasa

• Untuk Menghidupkan: Press the red power switch button (labeled with a power symbol) briefly. The device will begin a 30-second warm-up period.
• Untuk Mematikan: Press and hold the red power switch button for approximately 2 seconds until the screen turns off. The device will also automatically shut down after 4 minutes of no operation or gas detection.

5.2 Warm-up and Readiness

After powering on, the detector requires a 30-second warm-up time. During this period, the device prepares its sensor for accurate detection. Wait for the warm-up to complete before beginning gas detection.

5.3 Pelarasan Sensitiviti

The ANENG GN805 features adjustable sensitivity to suit different detection needs.

Figure 4: The 'S' button allows switching between high and low sensitivity modes.

• Press the 'S' key (Sensitivity Selection Key) to toggle between high and low sensitivity modes.
• guna Sensitiviti Tinggi for detecting very small leaks or for general scanning.
• guna Sensitiviti Rendah for pinpointing larger leaks or in environments where background gas levels might cause nuisance alarms on high sensitivity.

5.4 Proses Pengesanan Gas

To detect gas leaks:

1. Ensure the device has completed its warm-up period.
2. Move the sensor tip slowly towards the suspected leak area.
3. Observe the LCD display for gas concentration readings and listen for audible alarms.

5.5 Kaedah Penggera

The detector uses both visual and audible alarms:

• Penggera Visual: A red LED light will flash. The flashing rate increases with higher gas concentrations. The LCD display will also show a bar prompt indicating concentration levels.
• Penggera yang boleh didengar: A buzzer will sound. The urgency and frequency of the beeping increase as the detected combustible gas concentration rises.

5.6 Detectable Gases

The ANENG GN805 is capable of detecting a wide range of combustible gases, including but not limited to:

• Aseton
• asetilena
• Alkohol (Ethanol)
• Ammonia
• Benzena
• Epoxy Acetylene
• petrol
• Heksana
• Hidrogen
• Metana (Gas Asli)
• LPG (Gas Petroleum Cecair)
• Penipis Cat
• propana
• Pelarut

6. Penyelenggaraan

• Pembersihan: Lap peranti dengan kain lembut dan kering. Jangan gunakan pembersih atau pelarut yang melelas.
• Penggantian Bateri: Replace batteries promptly when the low power indicator appears to ensure accurate operation.
• Storan: Store the detector in a cool, dry place, away from direct sunlight and extreme temperatures, within the specified storage conditions.
• Penjagaan Sensor: Avoid exposing the sensor to moisture, acidic gases, or heavy dust, as this can impair its function or cause damage.

7. Penyelesaian masalah

• Peranti Tidak Dihidupkan: Periksa pemasangan bateri dan pastikan bateri segar.
• Bacaan Tidak Tepat/Penggera Palsu: Ensure the sensor is clean. Try adjusting the sensitivity setting. Avoid using in highly polluted environments or near strong odors that are not combustible gases.
• No Alarm for Suspected Leak: Ensure the device has completed its warm-up. Check sensitivity setting (try high sensitivity). Ensure the sensor tip is close to the leak source.
• Skrin Tidak Dipaparkan: Check battery level. If the issue persists after battery replacement, the device may require inspection.

If problems persist, refer to the warranty and support information or contact customer service.
