8.2 Important information for a correct positioning
In order to measure the night visibility (coefficient of luminous intensity R and R
respectively) of a road pavement marker, place the ZRP 6030+ over the road
pavement marker as evenly as possible. The measuring direction is indicated on
the ZRP 6030+ with an arrow.
The measuring area is indicated on the left and right side of the ZRP 6030+. When
positioning the reflectometer, the reflective area of the road pavement marker
needs to be centred in the measuring area.
