CHAPTER 1 • INSTALLING THE SMARTSENSOR ADVANCE 19
Aligning the Sensor
In most applications, the goal is to position the beam’s elliptical footprint along the roadway.
This is done by pointing the hot spot of the sensor’s beam (middle of the sensor) at a target
location, then rolling the sensor so that the beam’s footprint lines up with the road. After
the basic alignment achieved during the mounting process, the viewfinder is used to refine
the alignment.
About the Viewfinder
The viewfinder is a tool that helps you point the sensor at the target location and align the
sensor with the roadway (see Figure 1.6). It is designed with sighting features and visual
cues to facilitate proper alignment (these features and cues will be introduced from the
vantage point of an installer in a bucket truck).
Figure 1.6 – Viewfinder
The viewfinder has two main sighting features:
1 Target crossbars (top and bottom)
2 The long, narrow alignment bar
When the sensor is properly pointed at the target, the target will line up between the two
notches in the target crossbars, as shown in Figure 1.7.
