camera in the mirror up picture taking position). (Both of these tests must be done in a darkened aera.)
a. Static tests
(1)Erect the camera and remove the front cover assembly. Close S7.
(2)Turn on the power supply and insert the light leak fixture into the camera film compartment. The camera should run through the dark slide eject cycle.
(3)Darken room.
(4)Press and hold the fixture trigger.
(5)Examine the camera from all angles, looking for light leaks. Note the location of any light leaks and continue below with the dynamic test. (Leak are most likely at the hinge aera between the inner frame and mirror cover and at the boot tab aera).
b.Dynamic tests
(1)Cover the photocell lens and trip the shutter. With the photocell lens coveredn, the mirror should stay in the raised (picture taking) position long enough to perform the dynamic light leak test, approximately 13 - 28 seconds.
(2)Press and hold the fixture trigger.
(3)Examine the camera for light leaks. Gently flex the boot while looking for leaks. Note the location of any light leaks. (You may see a small amount of light in the aera where the boot joins the shutter housing. This is light emanating from the substrate and is normal.) Allow the camera
cycle completion and remove the fixture.
(4)Turn off the power.
(5)Repair any light leaks noted in the previous testing. If light leaks reparis are made, retest the camera.
5.Flash Simulator Board (Figure 3-9)
The Flash Simulator Board provides a quick, easy method for checking the flash firing capability of the
a. Insure that all switchers are in the position shown (down).
b. Insert a film pack or film pack simulator into the camera. Operating voltage is 5.0V to 6.4V.
