Operating Instructions—C-30B Camera
Once it is mounted, the camera can be swung away from
its adapter, to either side, by lifting the hinge pin on the
opposite side. The camera may be total ly removed from its
adapter by first lifting one pin, swinging the camera to one
side, then lifting the other pin. The adapter may also be de-
tached from the camera by lifting both hinge pins
simultaneously.
A slide on the adapter has been incorporated to provide
fo r easy camera mounting and removal. If a more secure
attachment is needed, tighten the two set screws (mounting
lock adjustments) located in the half-round boss on each
side of the adapter next to the light seal groove. Use a
5/64-inch hexagonal wrench fo r this purpose. To obtain
access to the two set screws, swing the camera away from
the adapter or remove the camera completely. These screws
need only be lightly tightened clockwise to lock the adapter
onto the oscilloscope bezel. To remove the adapter from
the bezel, loosen both set screws by turning them counter-
clockwise until the adapter is free to slide off.
NOTE
To ensure that the hinge pins w ill remain engaged in
the camera adapter when moving the instrument and
attached camera about, install a thumb screw into the
bottom o f each hinge pin after mounting the camera.
Before either o r both camera hinge pins can be lifte d
fo r swinging the camera out o r removing i t from the
adapter, the thumb screws must be completely
removed.
INSTALLING CAMERA BACKS
The choice of a camera back w ill depend primarily on
the intended use for the Photograph, how quickly you want
finished photographs, the area you wish to photograph, the
magnification factor of the lens, and the size of the picture
image desired.
Mounting procedures for each type of camera back
(Pack-Film, Roll-Film, and Graflok) are identical. Use the
following procedure to attach your camera back to the
C-30B. Figure 2-3 shows the example of a Pack-Film back
being mounted to the camera main frame.
1. Release the camera back latch by rotating it clock
wise.
2. T ilt the camera back as shown in Figure 2-3 until the
groove at its bottom is directly over the adapter clip
on the main frame.
3. Push the top of the camera back forward until it
snaps into place against the main frame.
4. Holding the camera back firm ly against the main
frame, rotate the camera back latch counterclock-
wise to secure the camera back.
5. To remove the camera back, release the latch by
rotating it clockwise. T ilt the top of the camera back,
then pull it out.
