Dynamic zoom


The currently moving axis can be geographically highlighted. In “dynamic zoom” mode, the position value is zoomed to its maximum size depending on the number of digits. This greatly improves legibility—especially from a great distance.

Installation guide


When you switch on the digital readout for the first time, the DRO203 supports you with an installation guide. You are led step by step through the most important settings until the device is ready for operation.

Day/night switching


Depending on the ambient-light conditions at the machine, you can switch the screen of the DRO203 to a light or dark background.
