shown in step one.

Lay the ¼” Spacer against the Filter Wheel and push the screws through the holes
provided in the filter wheel as shown in step 2.

Using the 9/64” Hex Wrench, tighten the Filter Wheel / ¼” Spacer combination onto the
entrance slit of the instrum ent as shown in step 3.

Using the 1/16” Hex Wrench, remove the cover to the TS-428 / TS-428-DC. See step 5.

Align the TS-428 / TS-428-DC’s shoulder screw slots with the shoulder screws that are

For proper operation, the lamp hou sing should be mounted to the en trance slit of the
spectrometer. The light collection mirror, located in the lamp housing, is designed to focus
light from the lamp onto the entrance slit of the spectrometer. To mount the lamp housing to
entrance slit, use the following procedure :

1. Locate the two (2) shoulder screws and the two (2) 8-32 cap screws supplie d with the TS-

428. Insert the shoulder screws into the tow bottom outside tapped holes of the entrance
slit of the spectrometer and tighten. These are used to mount the lamp housing.

2. Remove the four (4) slotted screws from the top of the lamp housing, then remove the
cover.

----------------------------------------------------------------------------------------------------­Do not touch the lamp (bulb) or the surface of the focusing mirror

-----------------------------------------------------------------------------------------------------

3. Carefully slide the two (2) “key hole” type slo ts of the lamp housing mounting flange
over the shoulder screws in the entrance slit of the spectrometer. Insure that the top tow
holes of the lamp housing mounting flange align properly with the top t ow tapped hole s
of the spectrom eter entrance slit.

4. Insert the two (2) 8-32 cap screws in the top tow holes of the lamp housing mounting
flange and tighten.

5. Replace the lamp housing cover.

6. Remove the (2) shoulder screws from the plastic bag. Insert the (2) shoulder screws in
the (2) tapped holes along the lower edge of the adapter plate.

7. Remove the four (4) slotted screws from the top of the light source, then remove the
cover.

-----------------------------------------------------------------------------------------------------

Do not touch the lamp (bulb) or the surface of the focusing mirror

-----------------------------------------------------------------------------------------------------

8. Carefully slide 2 of the 3 “key hole” type slots in the light source mounting flange over
the 2 shoulder screws in the adapter plate. The light sour ce mounting fl ange has (4)
clearance holes in line near the top edge. Assure that the inner pair of clearance holes in

7

the light source mounting f lange align properly with the two tapped holes along the upper
edge of the adapter plate.

9. Insert the (2) 8-32 x ½” cap screws from the plastic bag i n the inner pair of clearance
holes in the light source mounting flange and tighten.

10. Replace the light source cover.

The FA-448 Filter Assembly and Modified Light Source are now ready for use. Refer to the
