Grid Calibration:
It is also referred to as Non Linear Error correction (NLEC).
In this the entire measurement area is divided in to a grid. Each
grid cell compensates for variation with its own error correction
coefficient. It is mandatory to set the machine reference for each
axis before NLEC.
Specify the nominal and measured X and Y coordinates from the
standard during the setup process. NLEC requires a repeatable
machine zero defined on startup.

The changes will get saved in the memory and are applied.
The user will have to perform machine reference on every power
ON if SLEC is selected for an axis.
Machine Reference
Here the Machine reference can be set forthe selected axis. The
standard reference output from the encoder is used for referencing.
This is used only in case Segmented Linear compensation is to
selected.
