3.9 Measuring system changeover inch/metric

Function
This function allows you to change over between the two measuring
systems (inch/metric) according to the drawing's measurement
specifications.
You can change over the measuring system for the entire machine via
the "Inch" soft key in the extended soft key menu. After each
measuring system changeover your machine will show all dimensions
in "inch" or "metric".
At changeover, all necessary specifications are converted into the new
measuring system, e.g.
• positions
• tool offsets
• zero offsets.
Input values in the dialog boxes are not taken into account for the
measuring system changeover.
