"FNIRSI" LOGO appears on the LCD display, the device is turned on
▲ Power Off： Press and hold "⑧ Off/Clear key" for 3 seconds.When the LCD

1. The rangefinder cannot be moved during measurement, it needs to be placed
on a fixed support surface
2. Do not block the laser emission hole and the receiving lens during measurement
3. Based on physical principles, errors will occur when measuring on certain
surfaces, such as transparent, highly reflective, low reflective or porous surfaces.
Aiming targets can be placed on the above objects if necessary to improve
measurement accuracy
▲ Operation Precautions
2. Disadvantages: Refers to the weak reflectivity of the laser-irradiated area.(Like
black cardboard polished tiles.)The background lighting is strong and the working
temperature is <0°C or >45°C.At this time, an error effect of plus or minus 0.15
mm/m should be considered
