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
1. Opening the equipment by using tools (screwdrivers,etc.) without
allow.
2. Measuring to sun.
3. Others measuring out of appointed range.
4. Immersing the equipment in water.
5. Cleaning the lens using alcohol or any other organic solvent.
6. Wiping the lens directly with fingers or other rough surfaces.
7. Powering the equipment beyond the rated DC voltage.
