p Linear error correction (LEC)
LEC compensates for machine irregularities and encoder non-
linearities by applying a single linear correction value to the entire
range of measurement. To apply LEC to a measurement axis:
 Press MENU>Setup to display the Setup menu and then highlight the
Scale Factor menu item.
 Verify that the Active choice field specifies No.
 Highlight the SLEC menu item and verify that the Enabled choice
field specifies Off.
 Highlight the LEC menu item and make sure that all correction
values are 1.0.
 Highlight the NLEC Setup menu item and verify that the NLEC
choice field specifies Off.
 Position the standard artifact along the measurement axis.
 Align the artifact as closely as possible to the axis and then perform
a skew alignment as described in chapter 1 (see "Align the part to a
measurement axis" on page 32).
Notice
When scale factors are used, they must be applied after
error corrections.
Notice
LEC can not be performed if a different error correction is
already enabled.
