Horizontal checking
Two parallel wall surfaces at least 5m /16‘5“ apart are required for the
horizontal check.
1. Place the LA-5PG on a smooth surface or on a tripod as close
as possible to wall A and with the front side pointing towards the wall
2. Switch the unit on.
3. Mark the centre of the visible laser dot on wall A (point 1).
4. Turn the complete unit 180° without altering the height of the laser.
5. Mark the centre of the visible laser dot on wall B (point 2).
6. Now move the unit directly in front of wall B.
7. Set the unit‘s height so that the laser dot‘s height matches that of point 2.
8. Without changing the height of the laser, rotate it 180° to place the beam
near the mark on the first wall (step 3 / point 1 ).
