Encyclopedia : D : DI : DIG : Digital read out
A Digital Read Out (or DRO) is an electronic measuring instrument that converts the signal generated by a linear encoder and scale into a human readable form.
The display unit consists of a series of LEDs, or an LCD screen, to display the current position of the encoder on each scale. Each axis, such as X, Y or Z, that is provided with a scale, will have a dedicated display area where the measurement can be read and manipulated. DRO's allow for quick manipulation between methods of measurement (absolute or incremental), and conversion between imperial (inch) and metric units (mm) of measure. Modern DRO's enable limited calculations to be performed, such as co-ordinate positioning for the machining of holes around a pitch circle.
