2. Place a small amount of adhesive (Loctite

)
in the cut-out on the datum clamp, ensuring none
of the adhesive wicks onto the scale surface.
Dispensing tips are available.
1. Remove the backing paper from the datum clamp.
Place the datum clamp with cut-out against the scale
at the chosen location.
The datum clamp fixes the RTLC40-S scale rigidly to the substrate at the location chosen.
CAUTION:
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 customers’ requirements.

IMPORTANT:
Allow 24 hours after scale application before fitting datum clamp.
Ensure the adhesive wicks along
the entire length of cut-out.
