Passive. -Standard measuring equipment capable of measuring the force
values specified in 3.5.4 shall be utilized for this tests The
force required to disengage each boresight knob from the lock
position shall conform to the applicable requirements of 3.5.4 for
the temperatures indicated.
4.6.2.5 Rotation of boresiqht knobs - Dayliqht and Passive. -
Standard torque measuring equipment capable of measuring the torque
values specified in 3.5.5 shall be utilized for this test. An
appropriate adapter to accommodate the boresight knobs shall be used
with the torque measuring equipment. Torque shall be measured while
rotating each boresight knob through the range specified in 3.5.5.
The running torque required to rotate each boresight knob shall
conform to the applicable requirements of 3.5.5 for the temperature
indicated.
4.6.2.6 Shutter lever and on-off switch - passive. -Standard
torque measuring equipment capable of measuring the torque values
specified in 3.5.6 shall be utilized for this test. The torque

Manually operate the knob MS91528-OEIB. The knob shall meet the
requirements specified in 3.5.7, at the temperatures indicated in
0
3.4.2 in addition to the standard ambient temperature (73 18 F).
4.6.2.8 Focusing lock - Daylight. -A torque wrench capable of
applying the specified torque values in 3.5.8, together with a
standard type driver bit that properly fits the screw slot of the
locking screw and eccentric, shall be utilized for performing this
test. With the specified torque applied to the locking screw and
while observing the eccentric, apply in a clockwise direction, the
