20 CHAPTER 1 • INSTALLING THE SMARTSENSOR ADVANCE
When the sensor is properly aligned with the roadway, the long, narrow alignment bar will
line up with the center of the lanes of interest (see Figure 1.8).

In addition to having two main sighting features, the viewfinder is used from two different
viewpoints:
˽ Viewpoint 1 – Position your eye squarely behind the sensor. It is used to point the sen-
sor at the target and to align the sensor to the roadway.
The viewfinder has visual cues to help you achieve viewpoint 1: the two bottom side
tabs will line up between the target crossbars, and the bottom section of the long, nar-
row alignment bar will line up within the large notch (see Figure 1.9).
Figure 1.9 – Viewpoint 1
˽ Viewpoint 2 – This viewpoint is used to verify alignment down the center of the lanes
of interest. It allows you to view the upstream detection area of the sensor.
Viewpoint 2 is achieved by moving your eye down and in toward the viewfinder so that
the archway framed by the crossbar and the archway framed by the tabs are concentric
and the two top tabs match up with the top crossbar (see Figure #).
