4.6 Test methods and procedures.
4.6.1 Environmental.
4.6.1.1 Temperature test. - The telescope shall be subjected
to test Procedure I of MIL-F-13926; however, the temperatures
specified in 3.3.1, 3.3.2 and 3.3.3 shall apply. When the
telescope has been stabilized at the temperature specified, the
result of the specified test shall conform to the limits
outlined in 3.3.1, 3.3.2 and 3.3.3.
4.7 Performance
testing.
4.7.1 Orientation. - Proper orientation is assured when the
telescope is properly mounted and secured to a testing device,
the accuracy of which shall be equal to or exceed the accuracy
depicted in Drawing F8599924, and when aligned as outlined in
set-up instructions outlined on Drawing F8599924. When the
telescope is aligned as outlined above, set the mechanical cant
index line, and observe that the level vial position is as
specified in 3.6. During acceptance inspection, energize the
telescope's electrical system and observe that the illumination
of the level vial when energized with the voltage specified is
in conformance with 3.8.1. With the voltages specified in
3.8.2, observe that the reticle markings are in conformance
with 3.8.2 and also observe that a rotation of the rheostat
will cause illumination to increase from low to bright. Prior Prior
to performing acceptance inspection, remove image tilt by
unlocking the eyepiece portion of the telescope and rotating
the eyepiece until the longest reticle line is positioned
parallel to the comparable collimator target line. Lock in
this position.
4.7.2 Collimation.
4.7.2.1 Previbration. - With the telescope positioned as
outlined in 4.7.1, observe coincidence between the intersecting
point of the vertical reticle line designated as the normal
line for boresighting (N), to a comparable projector reticle
mark. This coincidence must be within the limits outlined in
3.7.1. Record this position, and observe coincidence for
conformance with 3.7.2. Inspect telescope for cleanliness
using techniques outlined in MIL-O-13830 for conformance with
3.4. Exercise care not to move telescope settings.
