6. Uputstvo za upotrebu
6.1 Mjerenje
Once powered on, the device will typically begin measuring oxygen concentration automatically. The electrochemical sensor provides a quick response.
- Ensure the sensor probe is exposed to the environment where oxygen concentration needs to be measured.
- The large LCD screen will display the current oxygen concentration in % VOL, along with temperature and humidity readings.
- Allow a few seconds for the reading to stabilize, especially when moving the device to a new environment.
6.2 Setting Alarm Levels
The ST8100A supports manual setup of high and low alarm levels, triggering both acoustic (beep) and visual (flash) alarms.
- Press the 'MODE' button to enter the alarm setting interface (refer to the display for specific indicators).
- Use the 'UP/SOUND' and 'DOWN/BACKLIGHT' buttons to adjust the desired high and low alarm thresholds.
- Press 'MODE' again to confirm settings and exit the alarm setup.
6.3 Izbor jedinice
If the device supports multiple units for measurement (e.g., for temperature), press the 'UNIT' button to cycle through available options.
6.4 Kontrola pozadinskog osvetljenja
Briefly press the 'DOWN/BACKLIGHT' button to toggle the LCD backlight on or off for improved visibility in different lighting conditions.
