2. Connect the two center points using a string. Extend the string an additional 5 m (16 ft) beyond the front centerpoint and mark
the floor. Position the target board weight on this mark.
3. Relocate the suspended string from the left side of the target board to the center of the target board. Mark this point on the ground.
4. Pivot the target board on its center mark 20 ° to either side.
NOTE:
Approx. 50 mm (1.97 in) shift will produce a 20 ° movement.
5. Remove any items in the shaded space shown in the figure.
NOTE:
In case the background space shown in the illustration is not available, or if the background is light col-
ored, place a 400 mm (15.75 in) long frosted black board or black cloth to both sides of the target board.
