2. Safety Information
WARNING: Laser radiation can be hazardous. Always follow proper safety procedures when working with lasers.
- Never look directly into the laser beam or its reflection.
- Wear appropriate laser safety eyewear when operating laser equipment.
- Ensure the laser power meter is correctly positioned before activating the laser.
- Do not expose the meter to excessive power levels beyond its specified range (0-200W).
- Keep the device dry and away from liquids.
- Do not attempt to disassemble or modify the device, as this may void the warranty and pose safety risks.

5. Operating Instructions
Follow these steps to accurately measure the power of your CO2 laser tube:
- Power On: Press the blue 'Start switch' button to turn on the device. The display will illuminate.
- Positioning: Carefully position the meter's 'Working Area' directly in the path of the laser beam. Ensure the beam hits the center of the photosensitive target area for the most accurate reading. The reduced photosensitive target area helps in achieving more precise measurements.
- Activate Laser: With the meter in position, activate your CO2 laser tube.
- Read Measurement: The display screen will show the laser power in watts. The status prompt code on the display provides intuitive feedback on the measurement status.
- Power Off: After measurement, turn off the laser, then press the blue 'Start switch' button again to power off the meter.

6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use abrasive cleaners or solvents. Keep the photosensitive working area free from dust and debris.
- Storage: Store the laser power meter in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, it is recommended to remove the batteries to prevent leakage.
- Calibration: While the device offers high-precision measurement, periodic professional calibration may be required to ensure continued accuracy, especially after prolonged use or if readings appear inconsistent.
7. Troubleshooting
- Problem: Display does not turn on.
- Solution: Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary.
- Problem: Inaccurate or inconsistent readings.
- Solution: Ensure the laser beam is centered on the photosensitive working area. Verify that the laser tube is stable and operating correctly. Clean the working area of the meter. If issues persist, consider professional calibration.
- Problem: Display shows an error code.
- Solution: Refer to the status prompt code for specific error indications. Common issues might include over-range measurement (laser power too high) or sensor malfunction. Discontinue use and contact support if the error persists.
