User Manual

the receiver’s elevation on the rod, the grade rod is then placed anywhere a
grade reading is needed.
When activated, grade-matching mode automatically adjusts the grade up or
down to “search” for the receiver. When the center of the receiver is found,
the resultant grade is calculated and dialed into the laser, and displayed on the
two-way radio remote control (if being used).
When grade matching is complete, the receiver can be removed from the
alignment point and the calculated grade will remain in the laser. Both axes of
the laser can be grade matched in sequence. Grade-matching mode is used
for applications where the existing grade is not known, but will remain
relatively unchanged (such as installation of a sidewalk or driveway).
PlaneLok Mode
PlaneLok mode works like grade-matching mode, except the receiver is
permanently mounted to the desired elevation so that the laser can use the
receiver to continually monitor beam elevation. The laser ignores the internal
level vial for that axis, using the absolute elevation from the receiver for level
control.
PlaneLok Mode is used for applications where extreme precision of the laser-
beam elevation is required, such as runway applications.
