5. Pag-setup
5.1. Pag-install ng Baterya
The ST8100B requires three (3) 1.5V AAA batteries for operation. Batteries are not included with the device.
- Hanapin ang takip ng kompartamento ng baterya sa likod ng device.
- Slide the cover open in the direction indicated.
- Insert three 1.5V AAA batteries, ensuring correct polarity (+/-) as marked inside the compartment.
- Isara nang maayos ang takip ng kompartamento ng baterya.
5.2. Unang Pag-on
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. Mga Tagubilin sa Pagpapatakbo
6.1. Pagkuha ng mga Pagsukat
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. Pagpapalit ng mga Yunit
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. Mga alarma
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) |
