5. Opstelling
5.1. Battery Installasie
The ST8100B requires three (3) 1.5V AAA batteries for operation. Batteries are not included with the device.
- Vind die batteryklepdeksel aan die agterkant van die toestel.
- Slide the cover open in the direction indicated.
- Insert three 1.5V AAA batteries, ensuring correct polarity (+/-) as marked inside the compartment.
- Maak die batterykompartement se deksel stewig toe.
5.2. Aanvanklike aanskakeling
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. Bedryfsinstruksies
6.1. Neem metings
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. Changing Units
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.
- Use the '▲' and '▼' keys to adjust the 'HI ALM' (High Alarm) value.
- Confirm the high alarm setting to save.
7. Alarms
The ST8100B is equipped with a high-decibel buzzer and a visual display alarm. When the detected oxygen concentration falls below the 'LO ALM' value or rises above the 'HI ALM' value, the instrument will activate both audible and visual alarms to alert the user.
8. Effects of Oxygen Concentration on Humans
Understanding the effects of varying oxygen levels is crucial for safety. The table below outlines the symptoms associated with different oxygen concentrations in the atmosphere (at standard atmospheric pressure).
| Oxygen Concentration (%) | Symptoms (Atmospheric Pressure) |
|---|---|
| 100% | Deadly, 6 minutes (Absolutely airtight environment, such as hyperbaric oxygen chamber) |
| 50% | Deadly, can be cured after 45 minutes treatment. (Absolutely airtight environment, such as hyperbaric oxygen chamber) |
| >23.5% | Rich oxygen |
| 20.96% | Normaal |
| 19.5% | Minimum |
| 15~19% | Reduce efficiency, and lead to problems of head, lung and circulation system |
| 10~12% | Shortness of breath, loss of judgment, purple lips |
| 8~10% | Governance loss, syncope, unconscious, pale, nausea and vomiting |
| 6~8% | 8 minutes, blood pressure, weak heartbeat, mouth breathing, quickly stopped breathing |
| 4~6% | 40 seconds, convulsions, respiratory arrest, death |
