Can a ZEISS CONTURA CMM be converted from VAST XT to RDS (or vice versa)?

ZEISS CONTURA or ZEISS CONTURA G2 units cannot be converted from VAST XT to RDS or vice versa.

However, an RDS-CAA can be retrofitted to a ZEISS CONTURA G2 Direct (with VAST XXT directly at the quill). Please note that the RDS with VAST XXT has different interference contours at the changing plate than the VAST XXT directly at the quill. The available measuring volume is thus smaller.
