Units
Your Digital Readout can be set to display position in either imperial or metric units of measure. Imperial units are displayed
in inches while metric units are in millimeters. Note that changing units will not affect current position and you may switch
the active units at any time.
The current units are indicated on the information screen. The feed-rate will be displayed in inches per minute (ipm) for
imperial units and in millimeters per second (mm/s) for metric units.
Standard Functions
Absolute and Incremental Modes
The use of absolute and incremental modes allows for different methods of referencing measurements. Proper use of these
modes allows the machinist to perform operations without the need for manual calculations. The currently active mode is
displayed on the information screen (“ABS” for absolute and “INC” for incremental).
When the DRO is in absolute mode , the coordinate display is always showing the position from the origin. In the example
part below, we set this origin point on the top surface at the front left corner of the part. If we were to move to drill feature
“A”, the DRO would display X=1.000” and Y=0.500”. To drill feature “B”, move the X axis until DRO displays X=1.800” .
In incremental mode , the coordinate display will show the position relative to the last feature. This can be helpful when
the working dimensions reference two features from each other. In the example part below, we would zero X and Y after
feature “A” is complete, and then move until DRO displays X=0.800” and Y= 0.300” to machine feature “C”.
