5. Setup and Charging
5.1 Initial Charge
Before first use, fully charge the device. Connect the provided Type-C cable to the charging port on the back of the detector and to a compatible USB power source (e.g., wall adapter, computer USB port). The device supports fast charging protocols (QC2.0, PD3.0, AFC, USB C UFP) with power supplies from 10W to 65W. A full charge typically takes approximately 2.5 hours.
5.2 Power On/Off
To power on the device, long-press the function button located on the front of the detector for 2 seconds. The display will light up and show readings. To power off, long-press the function button again until the display turns off.
6. Operating Instructions
6.1 Display Information
Once powered on, the LCD display will show the following information:
- Carbon Dioxide (CO2) concentration in ppm
- Carbon Monoxide (CO) concentration in ppm (for PTH-10D/E models)
- Temperature (in °C or °F)
- Humidity (in %)
- Battery level indicator
- Alarm status indicator
The display also features a color-coded ring around the main concentration reading:
- Green: Safe/Low concentration (e.g., CO2: 400-699 ppm, CO: 0-49 ppm)
- Yellow: Caution/Warning concentration (e.g., CO2: 700-1500 ppm, CO: 50-99 ppm)
- Red: Danger/Exceeds standard concentration (e.g., CO2: >1500 ppm, CO: >100 ppm)
6.2 Switching Detection Modes (PTH-10E)
For models that detect both CO and CO2 (PTH-10E), you can switch between displaying carbon monoxide and carbon dioxide concentration by a single short press of the function button after the device is powered on. This allows for quick and convenient monitoring of different gas types.
6.3 Changing Temperature Unit
To switch the temperature unit between Celsius (°C) and Fahrenheit (°F), short-press the function button while the device is displaying the current readings.
6.4 Customizing Alarm Values
You can customize the alarm thresholds for CO2 and CO concentrations:
- Double-click the function button to enter the alarm value setting mode.
- Short-press the function button to adjust the value of the currently flashing digit (tens, hundreds, or thousands place).
- Long-press the function button to confirm the digit and move to the next digit.
- Repeat the process for all digits (tens, hundreds, thousands) to set your desired alarm value.
- After setting, long-press the function button to save and exit. If no operation is performed for 15 seconds, the settings will be automatically saved, and the device will exit the setting mode.
6.5 Automatic Calibration (CO2)
To initiate automatic calibration for carbon dioxide:
- Ensure the device is powered off.
- Press and hold the function button during startup.
- The display will show "-CAL" and a countdown.
- Calibration will complete in approximately 200 seconds. During this time, ensure the device is in a fresh air environment for accurate calibration.
6.6 Alarm Sound Control
When an alarm sounds due to high CO or CO2 concentration:
- Short-press the function button to pause the alarm for 15 seconds.
- If the concentration remains above the set alarm value after 15 seconds, the alarm will resume.
- Short-press the function button again to restore the alarm sound immediately if it was paused.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid Obstruction: Ensure the vent holes on the device are not blocked to allow for proper air circulation and accurate readings.
- Battery Care: Recharge the device regularly to maintain battery health, even if not in frequent use. Avoid fully discharging the battery for extended periods.
- Environmental Conditions: While the device is designed for various conditions, avoid exposing it to excessive moisture, dust, or corrosive substances.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Low battery; Incorrect power-on procedure | Charge the device fully. Ensure you long-press the function button for 2 seconds. |
| Inaccurate readings | Sensor obstruction; Needs calibration; Extreme environmental conditions | Ensure vents are clear. Perform automatic CO2 calibration. Move to a stable environment. |
| Alarm sounds unexpectedly | High gas concentration; Alarm threshold set too low | Check air quality in the area. Adjust alarm thresholds if necessary (refer to section 6.4). |
| Display is blank or frozen | Device malfunction; Low battery | Recharge the device. Try resetting by long-pressing the power button. If issue persists, contact support. |
| Cannot switch temperature unit | Incorrect button press | Ensure you are short-pressing the function button while the device is on. |
9. User Tips
- Optimal Placement: For best results, place the detector at breathing height and away from direct drafts, windows, or vents that might skew readings.
- Regular Calibration: Although the device has automatic CO2 calibration, performing it periodically in fresh outdoor air can help maintain accuracy over time.
- Understand Alarm Levels: Familiarize yourself with the green, yellow, and red indicators and their corresponding concentration ranges for CO and CO2 to quickly interpret the device's warnings.
- Monitor Ventilation: Use the CO2 readings to assess ventilation in indoor spaces. Higher CO2 levels often indicate poor ventilation, which can be improved by opening windows or using air purifiers.
- Battery Management: Charge the device before long trips or outdoor activities to ensure continuous monitoring.
