I recently bought two of these - brand new old stock. I am looking to sell ONE of them for £300 plus postage.
It is designed to accept LS803 scales but according to the user manual it can be configured in the menu for other scales.
See user manual at:-
https://content.heidenhain.de/doku/o.../en/index.html Scroll down on the left to VRZ-710, select, and then scroll back up on the right and click on the English version.
I know that Chinese DRO consoles can be bought new for £300 but they are not the quality of these original DROs.
The unit has a few minor scratches from storage but it is clearly new/unused.
Cheers Carl.
