- 배터리 덮개를 단단히 닫으세요.
5.2. 초기 전원 켜기
Press and hold the On/Off button (usually the red power button) until the display illuminates. The device will perform a self-test and then enter the measurement mode.
6. 사용 설명서
6.1. 측정하기
Once powered on, the device will automatically begin measuring oxygen concentration in the surrounding environment. The current oxygen percentage and temperature will be displayed on the HD backlit LCD screen.
6.2. 단위 변경
Press the 'UNIT' key to cycle through available measurement units if applicable (e.g., for temperature display between Celsius and Fahrenheit).
6.3. Setting Alarm Values
The ST8100B allows you to set both low and high alarm thresholds for oxygen concentration.
- Enter the alarm setting mode (refer to the device's on-screen prompts or specific button combinations if available).
- Use the '▲' (Sound) and '▼' (Backlight) keys to adjust the 'LO ALM' (Low Alarm) value.
- Confirm the low alarm setting.
