3. Opstelling
3.1 Laai die toestel
The AS8906 detector is powered by a built-in 3.7V Li-battery. Before first use, ensure the device is fully charged.
- Locate the charging port at the bottom of the device.
- Koppel die meegeleverde USB-kabel aan die laaipoort.
- Connect the other end of the USB cable to the charging adapter.
- Plug the charging adapter into a standard power outlet.
- The battery indicator on the LCD screen will show charging status. A full charge typically provides up to 12 hours of continuous operation.

3.2 Koppel die SampLingpomp (Opsioneel)
The optional sampling pump (AS8930) is designed to assist the gas detector in environments with limited access or poor air circulation. It does not operate independently and requires power from the gas detector.
- Belyn die sampling pump with the gas detector's sampling pump connecting port.
- Securely attach the sampling pump to the gas detector using the two closed-type screws. Ensure a tight connection to avoid poor contact.
- Connect the soft rubber tube (500mm long) to the nozzle of the sampling pomp.
- Belangrik: Do not connect any other voltage power supply to the sampling pump to prevent damage.

4. Operasie
4.1 Aan-/afskakel
- Om aan te skakel: Druk en hou die Krag aan/af-knoppie until the LCD screen illuminates. The device will perform a self-test.
- Om af te skakel: Druk en hou die Krag aan/af-knoppie totdat die skerm afskakel.
4.2 Verstaan die skerm
The high-density digital LCD screen displays real-time gas concentration values, battery status, and other operational indicators. The backlight function allows for use in dark areas.
- PPM: Indicates parts per million, the unit for gas concentration.
- Battery-ikoon: Toon die huidige batterylaaivlak.
- Alarm aanwysers: Visual cues for alarm status.
4.3 Alarmfunksies
The device features high and low alarm functions with three alert methods: sound, light, and vibration. Alarm values are adjustable.
- When the gas concentration reaches a preset high or low alarm value, the device will activate its sound, light, and vibration alarms.
- The alarm sound can reach up to 80dB.
4.4 Adjusting Alarm Values
Refer to the on-screen menu for adjusting high and low alarm thresholds. Use the Up en Af buttons to navigate and change values, and the Voer in knoppie om te bevestig.
4.5 Using the Sampling Pomp
Wanneer die sampling pump is connected, it will draw air into the detector, allowing for gas concentration measurement in remote or confined spaces. The air flow velocity is approximately 0.5 cubic inches per hour, with a maximum gas sample collecting distance of about 50 feet.
5. Onderhoud
5.1 Batterysorg
- Recharge the device when the battery indicator shows low power to ensure continuous operation.
- Vermy om die battery gereeld heeltemal te leeg te maak om sy lewensduur te verleng.
- Indien die toestel vir 'n lang tydperk gestoor word, laai dit tot ongeveer 50% en herlaai dit elke paar maande.
5.2 Skoonmaak
- Vee die buitekant van die toestel af met 'n sagte, damp lap.
- Do not use abrasive cleaners or solvents, as these can damage the casing of skerm.
- Ensure no liquids enter the sensor area or charging port.
5.3 Kalibrasie
