2 PREPARATION FOR MEASUREMENT
7 Loosen the centering screw slightly.
Looking through the optical plummet eyepiece, slide the
instrument over the tripod head until the survey point is
exactly centered in the reticle.
Retighten the centering screw securely.
• When the instrument was centered using the laser
plummet, emit the plummet beam again to check
position over the survey point.
See “PROCEDURE: Centering with the laser
plummet (Option)”
