4. Uppsetning
4.1 Uppsetning rafhlöðu
- Finndu rafhlöðulokið aftan á tækinu.
- Opnaðu lokið með því að renna því eða skrúfa það af eins og sýnt er.
- Insert the specified batteries, ensuring correct polarity (+/-).
- Lokaðu rafhlöðuhólfinu tryggilega.
4.2 Upphafsvirkjun
After battery installation, press and hold the power button (usually located on the front or side) for a few seconds until the display illuminates. The device will typically perform a self-test upon startup.
4.3 Kvörðun
For optimal accuracy, it is recommended to perform an initial calibration or verify the factory calibration. Refer to the detailed calibration procedure in the full technical manual or contact UNI-T support for specific instructions. Regular calibration is crucial for reliable gas detection.
5. Notkunarleiðbeiningar
5.1 Kveikt/slökkt
- Til að kveikja á: Ýttu á og haltu inni rofanum þar til skjárinn virkjast.
- Til að slökkva á: Ýttu á rofann og haltu honum inni þar til beiðni um lokun birtist og staðfestu síðan.
5.2 Skilningur á skjánum
The high-definition color screen displays real-time gas concentration, unit of measurement, battery status, and alarm indicators. Consult the device's on-screen menu or full manual for detailed explanations of all display icons and readings.
5.3 Gasgreining
Once powered on, the detector continuously monitors the ambient air for Oxygen (O2) levels. Position the detector in the area where gas detection is required. The sensor draws in air via free diffusion.
5.4 Viðvörunaraðgerðir
The UT334-O2 is equipped with multiple alarm mechanisms:
- Heyranleg viðvörun: A loud beeping sound indicates an alarm condition.
- Sjónræn viðvörun: An alarm light (LED) will flash, typically red, to indicate an alarm.
- Titringsviðvörun: The device will vibrate, providing a tactile alert.
Alarm thresholds are typically pre-set but may be adjustable via the device's menu. Refer to the full manual for details on setting alarm points.
5.5 Curve Graph Display
The device can display a curve graph of gas concentration over time, allowing users to monitor trends and identify fluctuations in O2 levels. Access this feature through the device's menu.
6. Viðhald
6.1 Þrif
Wipe the exterior of the detector with a soft, damp klút. Notið ekki slípiefni eða leysiefni, þar sem þau geta skemmt casing or display. Ensure the sensor inlet is clear of dust and debris.
6.2 Skipt um skynjara
Gas sensors have a limited lifespan. When the sensor reaches its end of life or becomes faulty, it will need replacement. This procedure should only be performed by qualified personnel using genuine UNI-T replacement sensors. Refer to the technical service manual for detailed instructions.
6.3 Skipt um rafhlöðu
Replace batteries when the low battery indicator appears on the display. Follow the battery installation steps outlined in Section 4.1.
6.4 Geymsla
Store the detector in a cool, dry place away from direct sunlight, extreme temperatures, and corrosive chemicals. Ensure batteries are removed if the device will be stored for an extended period.
7. Bilanagreining
If you encounter issues with your UT334-O2 detector, try the following common troubleshooting steps:
| Vandamál | Möguleg orsök | Lausn |
|---|---|---|
| Ekki kveikir á tækinu | Töknar eða rangt settar rafhlöður | Skiptu um rafhlöður; gætið þess að pólunin sé rétt. |
| Ónákvæm lesning | Sensor contamination or out of calibration | Clean sensor inlet; perform calibration. |
| No alarm when gas detected | Alarm settings incorrect; speaker/vibrator fault | Check alarm thresholds in settings; contact support if hardware fault suspected. |
