Perform the following check after completing “Horizontal Calibration” on the previous page.

1
Set up the instrument half way between two
walls a minimum of 30 m (98 ft) apart. (The
instrument can be facing either direction X or
Y. No tripod is used.)

Turn the power switch on.
3
Place a piece of paper on each wall (A and B).
Mark the horizontal laser positions (Ma and Mb) on each wall using target.
4
Turn the power switch off. Position the
instrument for vertical operation (see
instruction on page 13) with the rotary head
directly facing wall A (see illustration). Make
sure the unit is level by checking the level vial.
Use the leveling screw to adjust if necessary.
5
Turn the power switch on. (Laser beam should
be in scanning mode.)
