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:
U Verify that the crosshair probe is selected. Press the PROBE soft
key to select it if necessary.
U Press MENU/SETUP to display the setup menu and then highlight
the Scale Factor menu item.
U Verify that the Active choice field specifies NO.
U Highlight the SLEC menu item and verify that the Enabled choice
field specifies OFF.
U Highlight the LEC menu item and make sure that all correction
values are 1.0.
U Highlight the NLEC setup menu item and verify that the NLEC
choice field specifies OFF.
U Position the standard artifact along the measurement axis.
U 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 34).
When scale factors are used, they must be applied after
error corrections.
LEC can not be performed if a different error correction is
already enabled.
