Comment:
*The deviation occurs under unfavorable conditions such as bright sunlight or when measuring too poorly reflecting or very rough surfaces, the environment temperature is too high or too low.
* When measuring distance within 10m, measurement accuracy is±1.5mm; more than 10m, measurement accuracy is calculated as follows:±1.5mm±0.05*(D-10)(D: Measuring Distance, Unit: m)
Forbidden
