winds and/or large temperature fluctuations, lower the Tracker
closer to the reference.
The following sections detail the positioning tracker in relation to
the grade reference, as well as on the machine.
Sonic Tracker Positioning in Relation
to Reference
Raise or lower the tracker bracket to position the tracker at the
proper height above the grade reference (Figure 6-1). The tracker
has a total working range of 14 to 55 inches. For paving
applications the recommended working height would be from 14 to
24 inches. At 55 inches the sonic footprint would be very large and
the tracker may pick up an undesired reference. The tracker also
compensates for temperature changes only within the bail range.
Placing the tracker too far from the reference may not allow for
accurate temperature compensation.
