Operation
example a passing vehicle, heavy rain, fog or snow is between the instrument and
the point to be measured, the EDM may measure to the obstruction.
•
Be sure that the laser beam is not reflected by anything close to the line of sight,
for example highly reflective objects.
•
When measuring longer distances, any divergence of the red laser beam from the
line of sight might lead to less accurate measurements. This is because the laser
beam might not be reflected from the point at which the crosshairs are pointing.
Therefore, it is recommended that the visible laser beam is aligned with the
center of the target. Refer to "14 Check & Adjust" for more information on how
to check the alignment.
•
Do not measure with two instruments to the same target simultaneously.
Guidelines for correct results:
•
Do not measure to glass prisms as this may lead to incorrect distance values.
