17.6 Setting the unit of measure
Application
This MOD function determines whether the coordinates are
displayed in millimeters (metric system) or inches.
Metric system: e.g. X = 15.789 (mm), the value is displayed to 3
decimal places

decimal places
If you would like to activate the inch display, the TNC shows the
feed rate in inch/min. In an inch program you must enter the feed
rate larger by a factor of 10.
