MIL-P-48619(AR)
locked after the diopter knob of the daylight eyepiece is set for
best focus of the periscope reticle;  the sector lever of test
fixture shall be engaged in the zero degree elevation position on
the index plate and the 10" collimator (80 field of view) shall be
adjusted for 1200 meters.  Light assembly "K" shall be removed when
performing tests for daylight system. When performing tests for
passive system, light assembly "K" shall be utilized.  The image
intensifier tube and reticle projector lamp shall be permitted a 15
second stabilization period, prior to conducting the performance
tests.
4.6.6.1 Electrical characteristics - passive.
4.6.6.1.1 Image intensifier tube. -Apply +24 VDC 6 VDC to
Contact 11733497 (Reference Drawing 11733401) and cycle the on-off
switch from off to on, by means of-the shutter lever.  After allow-
ing a 15 second tube stabilization period, view through the passive
eyepiece and observe the image tube screen.  The screen surface of
the image intensifier tube shall be illuminated.  Upon satisfactory
completion of the test, remove the 24 VDC 6 VDC from Connector
11733497 and apply 3 VDC 0.3 VDC to Connector 11733493 (Reference
Drawing 11733401).  Cycle the on-off switch from off to on. After
allowing a 15 second tube stabilization period, view through the
elbow assembly eyepiece.  The screen surface of the tube shall be
illuminated to determine overall compliance with 3.8.9.1.
CAUTION:  When the on-off switch is in the "On" position and the
input voltage to the regulator is interrupted, the tube cannot be
energized by reapplication of the input voltage unless the on-off
switch is cycled from-off to on.
4.6.6.1.2 Image steadiness. -Perform this test with the reticle
projector lamp off.  Position an observation telescope at the
passive eyepiece of the periscope.  The telescope shall contain a
crossline reticle pattern and be capable of focusing on the screen
of the image tube.  With the aid of the telescope, view through the
passive eyepiece and establish the telescope reticle crosslines
coincident to the projected target image crosslines.  Observe the
target image for a time period of not less than one minute.  During
this one minute time period there shall be no visual flicker, no
movement of the image nor audible sparking as specified in 3.8.9.2.
Image movement shall be determined by means of the target image with
respect to the observation telescope reticle pattern.  Sparking
shall be determined by means of an audio examination.  Upon
completion of this test, energize the reticle projector lamp.
