What is the measuring range and accuracy of the LS-P rangefinder? Under the general conditions of LS-P, the measuring range is 0.03-40 meters, and the measurement accuracy is ±2mm. The measuring range is 0.03-25 meters under adverse conditions, and the measurement accuracy is ±3mm. 2. What are the functions of the LS-P rangefinder? The LS-P rangefinder supports common single measurements, continuous measurements, angle display, front and rear reference switching, area measurement, volume, one PIP measurement, secondary pole measurement, one-button distance measurement and other practical functions. 3. Does LS-P last long? Is the usage cost high? The LS-P has a built-in 200mAh lithium polymer battery optimized by algorithms and a battery life of up to 3,500 measurements. After 5 minutes of charging, it can be continuously measured 300 times, and the battery consumption has almost no usage cost in the later stage. 4. How can I measure more accurately? In daily measurements, friends should keep the rangefinder static and not shake as much as possible; nor can it block the laser emission and reception window of the LSP. Based on physical principles, errors may occur when measuring on the surface of some objects. For example: a transparent surface (water surface, glass), a reflective surface (polished metal), a porous surface (sound insulation material), if necessary, a target (such as white paper) can be placed on the object to obtain accurate Oh, the data. 5. Are lasers safe? The internal LS-P laser is a Class 2 laser certified by the international laser IEC60825 and uses less than 1 mW. Daily use does not cause any harm to the human body. However, the high-brightness laser will cause visual damage to the eyes in the short term. Therefore, it is strictly forbidden to shoot directly at the eyes of people and animals to avoid accidental injury.
