3.2 Conectando o 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.
- Alinhe o 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 sampbomba de linguiça.
- Importante: Do not connect any other voltage power supply to the sampling pump to prevent damage.

4. Operação
4.1 Ligar/Desligar
- Para ligar: Pressione e segure o Botão liga/desliga until the LCD screen illuminates. The device will perform a self-test.
- Para desligar: Pressione e segure o Botão liga/desliga até que a tela desligue.
4.2 Compreendendo o visor
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.
- Ícone da bateria: Mostra o nível atual de carga da bateria.
- Indicadores de alarme: Visual cues for alarm status.
4.3 funções de 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 e Abaixo buttons to navigate and change values, and the Digitar botão para confirmar.
4.5 Using the SampBomba de ling
Quando o 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. Manutenção
