    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: Verify that the crosshair probe is selected. Press the PROBE soft key to select it if necessary.
  • Page 101 Perform a single measurement of the entire range of motion using the standard artifact and make a note of the result. Use an artifact that allows measurements of as much of the axis range of motion as possible. In this example of applying LEC, one point at end of the axis measurement range is measured using an 8 inch standard.

  • Page 102: Segmented Linear Error Correction (Slec)

    Segmented linear error correction (SLEC) SLEC compensates for machine irregularities and encoder non- linearities by applying correction values to individual segments that cover the entire range of motion along an axis. To apply SLEC to a measurement axis: Verify that the crosshair probe is selected. Press the PROBE soft key to select it if necessary.
  • Page 103 Verify that values in the LEC screen are Verify that NLEC (optional) Verify that the SLEC enable is OFF all 1.000 compensation is OFF Press MENU/CLEAR/CLR ALL 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"...
  • Page 104 To configure segmented linear error correction in the SLEC screen: Position the crosshair probe is over the zero reference of the standard artifact and press the AXIS key to zero the axis at the zero position of the standard. Highlight the SLEC menu item. Highlight the Axis choice field and select the axis for correction.

The system will enter the value measured at the end of the segment. In the example the Observed value at Station 3 is 2.98000.

  • Page 106: Nonlinear Error Correction (Nlec)

    Nonlinear error correction (NLEC) NLEC minimizes or eliminates the small inaccuracies in the X-Y measurement plane due to machine irregularities and encoder nonlinearity. Error correction coefficients are obtained by measuring a certified calibration grid. The actual values are then compared to the nominal grid values by the ND 1200.
  • Page 107 Highlight the SLEC setup menu item (if NLEC is present) and verify that the Enabled choice field specifies OFF. NLEC can not be performed if a different error correction is already enabled. NLEC correction can not be configured while NLEC is enabled. Highlight the NLEC setup menu item and verify that the NLEC choice field specifies OFF.
