Once set, the height will remain constant,
even when the transmission detector is
moved to the storage position as shown.
When rotated back to the working
position, the height will be correct.
When rotating the transmission detector,
do not “force” it at either end of travel.
The detector is held in position
magnetically, and will “snap” into
position as the magnets attract the striker
plate.
Note that the aperture should be in place
(as shown) when the tablet transmission
detector is used.
To remove the aperture (such as when
switching to reflectance use on a vial)
simply lift the aperture from its position.
Store in a safe place until use is again
required.
When installing or removing the aperture,
use the menu command to send the tray
to the Iris Position.
This command moves the sample carriage
mechanism out of the way, and allows
easy reach of the aperture plate.
It is important to position the aperture
correctly over the sample window.
This photo shows the underside of the
aperture, with short positioning pegs at
opposite corners. These must be placed
into the mating recesses on the sample
plate.
When in the correct position, the aperture
will be held in place magnetically.
