U
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.
Arrow number
Descriptions
1: Standard length
Entire 8 inch length is measured
2: Standard values
The certified length of the standard
3: Observed values
The measured length of the standard
4: Deviation graph
Difference between standard and observed
values (not entered into any screen)
To perform the linear error correction in the LEC screen:
U
Highlight the LEC menu item.
U
Enter the Standard value of the artifact and the Observed value
measured by the ND 1200 for the measurement axis. This example
shows Standard and Observed values for the X axis.
The standard and observed values for axes should be
1.000 when no LEC correction is applied.
Highlight the LEC screen
U
Perform LEC on other axes if desired and then press the FINISH key
to save parameters and return to the setup menu.
ND 1200 QUADRA-CHEK
Enter the standard and observed values
for the axis
