 Press MENU>Setup to clear all existing datums, part alignments and
part data.
 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).
In this example of applying SLEC, 4 points equally spaced along the
measurement range are measured using an 4 inch standard.
The deviation graph in the example at the right shows a datum zero
point and 4 certified and (corresponding) measured points. The
certified value at the end of each segment is entered into the Standard
data field manually using the Keypad. The actual measured value at the
end of each segment is entered into the Observed field automatically
by pressing the Teach softkey.
Verify that values in the LEC screen are
all 1.000 Verify that NLEC compensation is Off Verify that the SLEC enable is Off
