2. Awọn iṣọra aabo
Please read and understand all safety instructions before using the device.
- Aabo lesa: This product is a Class 2 laser product (<1mW). Do not look directly at the laser beam or point it at others.
- Awọn ipo Ayika: Do not point this machine directly at the sun or strong light to avoid damaging the internal photosensitive components of the machine.
- Yiye Iwọn: In harsh environments such as excessive sunlight or large temperature fluctuations, the reflection effect on the reflective surface may be weak. In this case, it is recommended to place a reflective board with better reflection ability on the surface being measured before proceeding with the measurement.
- Agbara Batiri: There will be significant errors in measurements when the battery power is low; it is recommended to replace the battery before proceeding with the operation.

9. Awọn imọran olumulo
- For best results, ensure the target surface is flat and perpendicular to the laser beam.
- When measuring long distances outdoors, especially in bright sunlight, consider using a target plate to improve laser visibility and accuracy.
- Always double-check your reference point (front or rear of the device) before taking critical measurements.
- Keep the laser lens clean to prevent measurement errors.
