Where:
STIR = the total indicator reading for the stationary machine.
ATIR = the total indicator reading for the adjustable machine.

HORIZONTAL ALIGNMENT
Once again, the horizontal alignment is performed exactly
the same as the vertical alignment, with the exception that both
indicators are set to zero on the left side or 9 o’clock position. Use
the same cautions and steps outlined for the vertical alignment to
