Targets; Reflector Rod - Hilti POS 15/18 Mode D'emploi

en
The laser beam takes measurements to "normal" surfaces without need for a special reflector.
"Normal" surfaces are considered to be those that are not highly reflective. These surfaces may have a rough texture.
Range depends on the reflectivity of the target surface, i.e. only slightly reflective surfaces such as those with a blue,
red or green color may reduce the effective range.
The tool is supplied complete with a reflector rod to which an adhesive reflective foil is attached.
Taking readings from this reflector ensures reliable distance measurements even at long range.
The reflector rod also allows distance measurements to be taken to points marked on the ground.
NOTE
Check at regular intervals to ensure that the visible laser distancer beam is correctly adjusted and in line with the
sighting axis. Send the tool to your nearest Hilti Service Center if adjustment is found necessary or if you are unsure.

6.3.2 Targets

The laser beam is capable of measuring to any stationary target.
While a distance is being measured care must be taken to ensure that no other object moves through the laser beam.
NOTE
There is otherwise a risk that the distance will be measured to another object, not to the desired target.

6.3.3 Reflector rod

The POA 50 (metric) reflector rod (consisting of four sections (each with a length of 300 mm), the rod point (length
50 mm) and the reflector plate (height 100 mm or, respectively, 50 mm to the middle)) is used to take readings from
points on the ground.
The POA 51 (imperial) reflector rod (consisting of four sections (each with a length of 12" ), the rod point (length 2.03")
and the reflector plate (height 3.93" or, respectively, 1.97" to the middle)) is used to take readings from points on the
ground.
The reflector rod can be held perpendicular to the ground or floor with the aid of the built-in bubble level.
In order to ensure an unobstructed line of sight for the laser beam, the distance between the tip of the rod and the
center of the reflector can be varied.
The pattern printed on the reflector foil ensures reliable measurement of distances and directions and allows a longer
range than is possible with other target surfaces.
