horizontal bars must be visible.
(8) Flip the HIGH/LOW switch to the HIGH position.
(9) again, look through the monocular and view the projected pat-
tern (see Figure 2.2.). If necessary, refocus the objective lens and
then the eyepiece lens to obtain the sharpest image.
(10) the MUnVM must be able to resolve Group 3, element 5, un-
der high light conditions to pass the test. If the monocular does not
pass the test, send it to a higher level of maintenance for repair.
NOTE
When using the TS-4348/UV Test Set, you are not viewing the
entire image intensifier. Therefore, operational and cosmetic
inspections must be done without the test set as specified in
paragraph 2.2.3.
(11) look for flashing, flickering, or other nonstable behavior of the
image intensifier. also check the image intensifier for other opera-
tional defects described in paragraph 2.2.3. to view the image in-
tensifier under low light conditions, flip the HIGH/LOW switch to the
LOW position and allow your eyes to become accustomed to the
dark. If any unacceptable conditions are noted, send to a higher
level of maintenance for repair.
