- Ensure the sensor inlet is free from dust and debris. Use a soft brush if necessary.
5.2 Сенсорду калибрлөө
To maintain accuracy, periodic calibration of the gas sensor is essential. This typically involves:
- Нөл калибрлөө: Performed in a clean, fresh air environment free of the target gas. This sets the baseline for zero concentration.
- Кеңири калибрлөө: Performed using a certified calibration gas of known concentration. This adjusts the sensor's response to the target gas.
Refer to the device's menu for calibration options. It is recommended to follow a regular calibration schedule as per industry standards or manufacturer guidelines, typically every 6 to 12 months, or if readings appear inaccurate.
5.3 Батареяга кам көрүү
- Charge the battery fully before first use and whenever the low battery indicator appears.
- Батареянын кубатын тез-тез толугу менен түгөтүп коюудан алыс болуңуз, анткени бул анын иштөө мөөнөтүн кыскартышы мүмкүн.
- Эгерде түзмөктү узак убакытка сактасаңыз, батареяны болжол менен 50% га чейин заряддап, салкын, кургак жерде сактаңыз.
