Note the use of a handheld laser rangefinder.
1. Pay attention to the positive and negative poles when installing the battery, and only use alkaline batteries.
2. When measuring, do not point the laser directly at the sun, eyes, or irradiate eyes through reflective surfaces (such as specular reflection).
3. Use it with care and avoid placing it in places that are too humid, high temperature or direct sunlight.
4. The sun is too strong, the ambient temperature fluctuates too much, the reflection effect of the reflective surface is weak, and the measurement result has a large error when the battery power is insufficient. In this case, it is better to use with the target reflector.
