Calibration of device (calibratoin of load & displacement).
It allows any capacity of load cell to work on same device,
adjustments of least count, overload and over displacement settings
etc.

Graph setting includes Maximum scale values of load/displacement
to be drawn. Auto zoom feature when enable zooms the graph for the
specific test to view full screen, after the completion of test
automatically.
