line and raise or lower the target to obtain coincidence between the
target horizontal line and the horizontal reticle line of the panoramic
telescope's reticle. The plumb travel test is performed by actuating the
panoramic telescope's elevation knob from the zero setting to each extreme.
The line of sight must travel to the limit lines of the target to assure
compliance with 3.8.1.1 and must follow the plumb from zero elevation
within the width of the reticle line to assure compliance with 3.8.1.2.
4.7..2.4 Operability. - When the panoramic telescope has been stabilized
at the temperatures specified in 3.9, tactile inspection techniques shall
be used to determine compliance outlined in 3.9.
4.7.2.4.1 Torque. - Torque tests shall be performed under temperature
conditions outlined in 3.9.1. The torque tests shall be performed using
a torque wrench and appropriate adapter. The torque readings obtained
shall conform to the limits specified in 3.9.1.
4.7.2.5 Illumination. - Electrically connect a power source to the
panoramic telescope capable of producing 24 6 vdc and energize
the appropriate lamps and visually inspect to determine compliance with
3.10.1, 3.10.2 and 3.10.3. Rotation of the rheostat knob from the off
position shall increase intensity of illumination from dim to bright and
the projector light shall be visible within the limits outlined in 3.10.2.
4.7.2.6 Counter numbers. - By means of standard measuring equipment
determine digit alignment in accordance with 3.9.2.3.
4.7.2.7 Force applied to elbow assembly. - Secure an appropriate
adapter to the elbow assembly at the eyepiece assembly and apply a push
The force required to move the elbow assembly thru full travel
shall not exceed the limits outlined in 3.9.2.1 for the temperatures
specified.
4.7.2.8 Reset conter force. - Secure an appropriate adapter to the
reset counter and apply a pushing force to disengage the locking mechanism
of the reset counter. This force will be measured when the reset knob is
permitted to rotate and shall not exceed the limits of 3.9.2.2.
4.7.2.9 Insulation resistance. - This test shall be performed as
outlined in Test Method 302 of MIL-STD-202, using test condition "A".
The test shall be made between insulated points and ground. Resistance
shall not be less then the value specified in 3.11.
4.7.2.10 Continuity. - Use standard shop type continuity checks in
conjunction with standard inspection techniques to determine conformance
with 3.12.
5. PREPARATION FOR DELIVERY
5.1 Packaging, packing and marking. - Packaging, packing and marking
shall be in accordance with Specification MIL-P-14232 and packaging Data
Sheet 10555974. The level of protection shall be as specified in the
procurement document.
