„ To select the metric system (e.g. X = 15.789 mm), set the Change
mm/inches function to mm. The value is displayed to 3 decimal
places.
„ To select the inch system (e.g. X = 0.6216 inches), set the Change
mm/inches function to inches. The value is displayed to 4 decimal

If you would like to activate the inch display, the TNC shows the feed
