Scale Datum - Renishaw QUANTiC RTLC40 Installation Manual

Scale datum

The datum clamp fixes the RTLC40 scale rigidly to the substrate at the location chosen. The metrology of the system may be compromised if the datum clamp is not used.
The datum clamp does not need to be fitted adjacent to a reference mark. It can be positioned anywhere along the axis depending upon the customer's requirements.
