The target fixture is difficult to fine tune, adjusting the feet of the tripod to the bubble levels on the target is best.
The laser included with the tool is used only to help aim the target, it must be removed from the target prior to calibration.
Masking tape and a tape measure may be used during alignment.
Be sure to make as square as possible measurements.
