4. Setup
4.1 Battery Installation
- Locate the battery compartment on the back of the device (refer to Figure 2, "Battery Door").
- Open the battery compartment cover.
- Insert three (3) AAA 1.5V Alkaline batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
Note: Batteries are not included with the device. Always use new, high-quality alkaline batteries for optimal performance.
5. Operating Instructions
5.1 Power On/Off
- To power on the device, press and hold the Power On/Off Key (labeled with a power symbol) for approximately 2 seconds. The device will perform a self-test and then display current CO and temperature readings.
- To power off the device, press and hold the Power On/Off Key again for approximately 2 seconds until the display turns off.
5.2 Carbon Monoxide Measurement
Once powered on, the meter will continuously display the current carbon monoxide concentration in parts per million (PPM) and the ambient temperature. The gas sensor is located at the top of the device.

5.3 Alarm Settings
The device has a preset alarm point of 24 PPM. This value is adjustable.
- To adjust the alarm point, press the SET Key (High and Low Concentration Alarm Setup Key).
- Use the UP (UNIT) and DOWN (MODE) keys to increase or decrease the alarm value.
- Press the SET Key again to confirm and save the new alarm point.
When the CO concentration reaches or exceeds the set alarm point, the device will emit a sound alarm and the display will flash.
5.4 Unit Selection (Temperature)
To switch between Celsius (°C) and Fahrenheit (°F) for temperature display:
- Press the UNIT Key (Up arrow) briefly. The temperature unit on the display will toggle between °C and °F.
5.5 Data Hold Function
To freeze the current CO and temperature readings on the display:
- Press the MODE Key (Data Hold Key) briefly. The "HOLD" indicator will appear on the screen.
- Press the MODE Key again to exit data hold mode and resume real-time measurements.
5.6 Auto Power Off
The device is equipped with an auto power-off function. If no operation is performed for 10 minutes, the meter will automatically shut down to save battery life. This feature can help prevent accidental battery drain.
6. Maintenance
6.1 Cleaning
- Wipe the device with a soft, dry cloth.
- Do not use abrasive cleaners, solvents, or corrosive chemicals, as these can damage the casing or internal components.
- Ensure no liquids enter the sensor opening or other openings.
6.2 Storage
- When storing the device for extended periods, remove the batteries to prevent leakage.
- Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
- Keep out of reach of children.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed batteries. | Check battery polarity. Replace with new AAA batteries. |
| Inaccurate readings. | Sensor obstruction or damage; low battery. | Ensure sensor is clear. Replace batteries. If problem persists, contact support. |
| Alarm sounds unexpectedly. | High CO concentration detected; alarm point set too low. | Evacuate and ventilate the area immediately. Check and adjust alarm point if necessary. |
| Auto power off too soon/not working. | Normal operation (10 min inactivity); internal fault. | Auto power off is a feature. If it powers off immediately after use, contact support. |
