8. Self-Check & Fine Calibration

IMPORTANT: 

It is the responsibility of the user to verify the 

calibration of the instrument before each use.

The instrument must be self-checked for accuracy periodically,
specifically before a large project, where accuracy is critical.  If the
accuracy is found to be beyond tolerance, some adjustment may be
made as follows.

X-Axis and Y-Axis Accuracy Check:

1. Place a table indoors, approximately 20m from a wall.  Place the

instrument on the table with the X-axis facing the wall.

2. Power the instrument on and allow it to self-level.  Adjust the 

rotating speed to make the output laser line clear and visible.
Mark a vertical line on the wall that intersects the laser line from
the instrument.  Mark a line where the laser line hits the vertical
line, and label as ‘A’.
