4. Operating Instructions
4.1 Display Overview
Image 4.1: Close-up of the monitor's HD color screen, illustrating the display of PM values, CO2, HCHO, TVOC, temperature, humidity, and the color-coded AQI bar.
The monitor features a high-definition color LCD screen that displays various air quality parameters simultaneously. Readings are updated every 3 seconds. The display uses a color-coded system for quick interpretation:
- Green: Indicates good air quality.
- Yellow: Indicates acceptable or "OK" air quality, suggesting attention may be needed.
- Red: Indicates poor air quality, requiring immediate action.
4.2 Button Functions
The device typically has several buttons for control:
- Power Button:
- Long press: Turn the device on or off.
- Long press for 5 seconds: Resets all values to factory defaults.
- Time/Unit Switch Button:
- Short press: Switch between 12-hour and 24-hour time formats.
- Long press (approx. 5 seconds): Adjust the time settings.
- Short press: Switch between Celsius (°C) and Fahrenheit (°F) for temperature display.
- Sound/Buzzer Button:
- Short press: Turn the audible buzzer alarm on or off.
- Double-click: Silence active alerts.
- Light/Brightness Button:
- Short press: Cycle through 3 levels of display brightness.
4.3 Understanding AQI Alarms
The monitor is equipped with 7 types of AQI alert buzzers. When air quality parameters exceed predefined thresholds, the device will emit an audible alert. For example, if air quality is "POOR" (beyond normal range), the device may emit two longer "BBB, BBB" sounds.
Refer to the table below for specific thresholds and corresponding alert behaviors:
Image 4.2: Detailed table outlining the thresholds for various air quality parameters (PM1.0, PM2.5, PM10, CO2, TVOC, HCHO, AQI) and their corresponding "Good," "OK," and "Poor" classifications, including buzzer alert information.
| Parameter | GOOD | OK | POOR |
|---|---|---|---|
| PM1.0 | ≤50 ug/m³ | 50-150 ug/m³ | >150 ug/m³ |
| PM2.5 | ≤50 ug/m³ | 50-150 ug/m³ | >150 ug/m³ |
| PM10 | ≤50 ug/m³ | 50-150 ug/m³ | >150 ug/m³ |
| CO2 | <800 ppm | 800-1500 ppm | >1500 ppm |
| TVOC | <0.6 mg/m³ | 0.6-1.5 mg/m³ | >1.5 mg/m³ |
| HCHO | <0.08 mg/m³ | 0.08-0.1 mg/m³ | >0.1 mg/m³ |
| AQI | 0-50 | 51-150 | 151-500 |

7. Troubleshooting
If you encounter issues with your AQItech Air Quality Monitor, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or no charge. | Connect the device to a power source using the USB-C cable and allow it to charge for at least 30 minutes before attempting to power on again. |
| Inaccurate or fluctuating readings. | Device is in a dusty environment, near strong air currents, or recently moved. | Place the device in a stable, calm environment away from direct drafts or strong odors. Allow several minutes for readings to stabilize. Perform a factory reset if issues persist (long press power button for 5 seconds). |
| Buzzer alarm sounds continuously. | Air quality parameters exceed "POOR" thresholds. | Check the display for specific parameter readings. Improve ventilation (e.g., open windows). Double-click the sound button to temporarily silence the alarm. |
| Display is dim or unresponsive. | Brightness setting is low or device is in power-saving mode. | Short press the Light/Brightness button to cycle through brightness levels. Ensure the device is charged. |
| Cannot switch temperature units or adjust time. | Incorrect button press duration. | Ensure you are using a short press for unit switching and a long press (approx. 5 seconds) for time adjustment on the designated button. |
