Dynamic zoom
The currently moving axis can be enlarged.
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 DRO300 supports you with an installation guide. You are led step by step through the most important settings until the device is ready for operation.
