There is a possibility that correct distance measurement may be impossible by
dispersion or reduction of laser beam when the laser beam comes into the target from
diagonal angle.
There is a possibility that the instrument cannot calculate correctly when receiving
reflected laser beam from forth and back directions in case of measuring the target on
the road.
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 cannot calculate correctly collecting the
reflected laser beam from a man or a car that comes and goes in front of the target.
[Distance measurement by reflector sheet mode]
Position the Reflector sheet whose reflecting surface faces the aiming line to be approx.
right angle when the distance is measured by it.If it is positioned not to be approx. right
angle,there is a possibility that correct distance measurement may be impossible by
dispersion or reduction of laser beam.
[Applied measurement range by each target mode]
• When a wrong target mode is selected,a correct distance cannot be measured.
Please select a correct target mode and measure.
• Reflector sheet mode and prism mode:
It is sometimes possible to measure without reflector sheet or prism under special
conditions like in the close distance,targeting on a wall surface.
However,there is a possibility including some errors in this case,so be sure to select
the reflectorless mode.
• The target constant should be correctly selected and confirmed in case that the
reflector sheet is used at the prism mode and the prism is used at the
reflector sheet mode.
