For jobs with multiple elevations, the vibration pole and Trackerjack
can be adjusted as needed, providing over 9 feet of elevation
adjustment.
Figure 4-19.
For Laser Trackerjack application, it is best to set the reference
number so that when the cutting edge is at Finished Grade, the
reference number is either set to a known elevation or set to 0.00.
To set the reference number, first set up the Laser Transmitter for the
job application. Then place the grade rod on the reference hub and
move the detector up or down to lock on the laser beam. Adjust the
rod for cut/fill or known elevation of the reference hub.
