Calibrating NLEC by adjusting station values
The process of calibrating by adjusting sta-
tion values is shown by this chart and de-
scribed below. This process is generally used
to adjust existing NLEC calibration data.
1 Make sure that NLEC is disabled (En-
abled checkbox is cleared).
2
Define the grid. The grid size and cell
size data entry fields are shown at the bot-
tom of the NLEC setup screen. Enter the grid
size in terms of the number of X and Y grid
points, and then enter the cell size in terms of
the distance between points.
3 Load an .acf file of certified values if
desired. Insert a USB drive into the USB port
containing the nlec.acf file at the root of the
drive, and the touch the Import/Export but-
ton. A pop-up window
will display the Import/
Export choices. Touch
the Load Acf button.
4
Exit the setup mode, measure the skew through the
bottom grid points of the calibration grid and create a zero
datum at the lower left point of the grid.
