4.1 Limen/Etenyen
- Pou limen: Peze epi kenbe la Bouton On/Off until the LCD screen illuminates. The device will perform a self-test.
- Pou etenn: Peze epi kenbe la Bouton On/Off jiskaske ekran an etenn.
4.2 Konprann ekspozisyon an
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.
- Ikon batri: Montre nivo chaj batri aktyèl la.
- Endikatè alam: Visual cues for alarm status.
4.3 Fonksyon alam
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 epi Desann buttons to navigate and change values, and the Antre bouton pou konfime.
4.5 Using the Sampling Ponp
Lè s laampling 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. Antretyen
5.1 Swen Batri
- Recharge the device when the battery indicator shows low power to ensure continuous operation.
- Evite vide batri a nèt souvan pou pwolonje dire lavi li.
- If storing the device for an extended period, charge it to approximately 50% and recharge every few months.
