*Under the condition of poor measurement(Such as ambient light is too strong,diffuse feflectivity of the measured point is too large or too small)Measurement accuracy will have a greater error ¡À1mm+400PPM
**Under the strong sunlight or the measurement target reflection is not good,please use the Chopping block.
***In od outdoor mode,the laser power will increase to about 2.5mW,please use it cautiously.
