Operating sequence
"AUTO"/"MDI"/"Jog" mode is selected in the "Machine" operating
area.
Press the ETC key followed by
the softkey "Switch to metric".
When the system of measurement is changed, all length-related
parameters are automatically converted to the new system of
measurement from the perspective of the operator.
If the switchover cannot be performed, this is indicated by a message
in the user interface.

Warning
If several NCUs are linked by an NCU link, then the switchover affects
all linked NCUs. If the prerequisites for a switchover are not fulfilled on
one of the NCUs linked, no switchover will take place on none of the
NCUs. It is assumed that interpolations between several NCUs will
take place on the existing NCUs whereby the interpolations can
provide correct results only if the same unit systems are used.
