NOTES:
X
Datum clamp usually coincident with selected
IN-TRAC reference mark. However the
position is user-selectable depending upon
application.
For lengths 80 ≤ L ≤ 190 ensure scale is
X
clamped or clipped in the middle as well as at
both ends.
X
For optimum performance the readhead should
be installed close to nominal geometry.
X
Care should be taken to ensure sufficient
clearance between the readhead/mounting
bracket and clips/datum clamp.
X
Only special low‑profile screws should be
used. Screws are provided with all clips/datum
clamps and spares can be supplied if required.
*
Clips omitted for clarity. Reference marks
positioned equidistant from scale ends.
