3.2 Cunnettendu u Sampling Pump (Optional)
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.
- Allinea u 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 pump.
- Impurtante: Do not connect any other voltage power supply to the sampling pump to prevent damage.

4. Operazione
4.1 Accensione / spegnimentu
- Per accende: Appughjà è tene premutu Pulsante Power On/Off until the LCD screen illuminates. The device will perform a self-test.
- Per spegne: Appughjà è tene premutu Pulsante Power On/Off finu à chì u screnu si spegne.
4.2 Capisce u Display
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.
- Icona di a batteria: Mostra u livellu attuale di carica di a batteria.
- Indicatori d'alarme: Visual cues for alarm status.
4.3 Funzioni di alarme
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 è Giù buttons to navigate and change values, and the Entre buttone per cunfirmà.
4.5 Using the Sampling Pump
Quandu u 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. Mantenimentu
5.1 Cura di a batteria
- Recharge the device when the battery indicator shows low power to ensure continuous operation.
