• There is a possibility that synthesized values are calculated and the distance may become longer or shorter than the actual one when the operator measures the target of slope or sphere or rugged shape.
• There is a possibility that the instrument may not be able to correctly calculate out the distance by collecting the reflected laser beam from a man or a car that comes and goes in front of the target.
• There is a possibility that the distance may not be correctly measured when measuring a target in the direction where there is a reflecting object (mirror, stainless board, white wall, etc.) or under too strong sunlight.
• In a situation where high accuracy may not be expected, perform the measurement by
Reflector sheet or Prism.
• When using reflector sheet, set the reflector sheet to have its surface to be approx. vertical to the aiming line. If it is positioned not to be approx. right angle, there is a possibility that correct distance measurements may be impossible by dispersion or reduction of laser beam.
In the following environments, the distance may not be possible to be measured; there is a reflecting thing (mirror, stainless board, white wall, etc.) in the direction of the target, and under too strong sunlight
