Reflectorless EDM, continued
Inspection
A target plate is provided. Set it
up between five and 20 metres
away with the grey reflective
side facing the instrument. Move
the telescope to face II. Switch
on the red laser beam by
activating the laser-point
function. Use the telescope
crosshair to align the instrument
with the centre of the target
plate, and then inspect the
position of the red laser spot on
the target plate. Generally
speaking the red spot cannot be
seen through the telescope, so
look at the target plate from just
above the telescope or from just
to the side of it. If the spot illuminates the cross,
the achievable adjustment
precision has been reached.
If it lies outside the limits of the
cross, the direction of the beam
needs to be adjusted.
If the spot on the more reflective
side of the plate is too bright
(dazzling), use the white side
instead to carry out the
inspection.
