Procedure for Checking Alignment Telescope
Principle of Check:
The procedure for checking the alignment of ELDS alignment telescopes makes use of the
principle that a correctly aligned telescope points in exactly the same direction whatever the angle
of rotation with respect to the alignment datum. This principle means that if you rotate an
alignment telescope about an ELDS unit’s alignment datum, the crosshairs on a correctly aligned
telescope will remain centred on the same point / object within the telescope’s field-of-view. If
rotating an alignment telescope about the alignment datum results in significant movement of the
crosshairs relative to the original point / object, the alignment telescope is not correctly aligned.
CAUTION
The alignment telescope is a precision optical alignment device. Dropping or mishandling of the
alignment telescope may result in the telescope becoming incorrectly aligned.
IF you DROP or DAMAGE an alignment telescope STOP using it; and either CHECK that the
alignment is still good using the process described below, or RETURN it to Senscient for
checking and re-alignment.
Notes:

The procedure for checking alignment telescopes depends upon the use of an ELDS unit that
is mounted upon an extremely stable, rigid mounting structure. Only attempt to verify the
alignment of an alignment telescope on an ELDS unit mounted on the most rigid and stable
structure available.

Do not attempt to check alignment telescopes on ELDS units that are mounted upon structures
that can flex or move.

Do not attempt to use this procedure to adjust the alignment of alignment telescopes. If an
alignment telescope fails this alignment check it must be returned to Senscient for re-
alignment.
