4. Setup
4.1 Installazione di batterie
- Truvate u coperchiu di u compartimentu di a batteria nantu à u spinu di u dispusitivu.
- Open the cover by sliding or unscrewing it as indicated.
- Insert the specified batteries, ensuring correct polarity (+/-).
- Chiudere in modu sicuru u coperchiu di u compartimentu di a batteria.
4.2 Power-On iniziale
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 Calibrazione
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. Operating Instructions
5.1 Accensione / spegnimentu
- Per accende: Appughjà è tene premutu u buttone di accensione finu à chì u schermu si attiva.
- Per spegne: Press and hold the power button until a shutdown prompt appears, then confirm.
5.2 Capisce u Display
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 Detection Gas
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 Funzioni di alarme
The UT334-O2 is equipped with multiple alarm mechanisms:
- Alarme sonore: A loud beeping sound indicates an alarm condition.
- Alarma visuale: An alarm light (LED) will flash, typically red, to indicate an alarm.
- Alarma di vibrazione: 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. Mantenimentu
6.1 Pulizia
Wipe the exterior of the detector with a soft, damp pannu. Ùn aduprate micca detergenti abrasivi o solventi, postu chì questi ponu dannà u casing or display. Ensure the sensor inlet is clear of dust and debris.
6.2 Rimpianu Sensor
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.
