6.2. Зміна одиниць

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.

  1. Enter the alarm setting mode (refer to the device's on-screen prompts or specific button combinations if available).
  2. Use the '▲' (Sound) and '▼' (Backlight) keys to adjust the 'LO ALM' (Low Alarm) value.
