I. DESCRIPTION
This table provides an I l'? by 40" illuminated area for use in viewing
9-1/2" to 2-3/4?? (i,e, , 70mm.) film inclusive, or dual rolls of either 70mm
or 5" film. concurrently, A movable microscope carriage affords trans-
lation of a microscope with a graduated microscope movement and tracking
light sources over the viewing area, The table can be horizontally tilted
for operator convenience.

II. SETUP OF LIGHT TABLE FOR OPERATION
A. SUPPORT OF THE LIGHT TABLE
The table must be leveled on.a rigid support, Leveling will ac-
complish the freest operation of the microscope carriage; the rigid support
will make possible the most accurate results when making a measurement,
Leveling of the table is accomplished by adjusting the height of the four
leveling pads (#1 Figure 1). Loosen the screw (#2 Figure 1), raise the
table to the desired point, and tighten the screw securely,
B. HEIGHT ADJUSTMENT OF THE LIGHT TABLE
An increase in height of two nc.hes can be gained by lowering the
leveling pads (#1 Figure 1), (See above paragraph for height adjustment. )
C. TILTING THE LIGHT TABLE
The table can be tilted from 00 to 8? with respect to the horizontal
by proper adjustment of the leveling pads (#I Figure 1), For maximum tilt
the front leveling pads must be fully retracted and the rear pads fully ex-
tended. (For adjustment of the pads, see paragraph U, A. above. )
CAUTION: When the table is tilted, the microscope carriage is
free to roll if the Y?-Y brakes (#3 Figure 1) are not
locked, The microscope carriage will be damaged if
it falls free and strikes the stops (#4 Figure 1).
D. APPLYING POWER TO THE LIGHT TABLE
1. Connect the Master Control Panel (#I Figure 1) to the
Master Control Panel (#2 Figure 2) and to the proper connector
in the side of the light table,
2. Connect the .120-volt 60mcyclepower cords (#3 Figure 2) to the
light table and the power line.
WARNING: THIS TABLE TO BE USED ONLY WITH 120 VAC
60-- C YCLE WITH-i A 3RD GROUND WIRE, BE
SURE THE TABLE IS ALWAYS ELECTRICALLY

CAUTION: When Viewing 9, 5" Film, The Direction Switch
(#5 Figure 3) Must Be In The (Same
Direction).
D. LOADING OTHER SIZE FILM
This table is designed. to accommodate film. widths ranging from
70m.m to 9e 5", However, when film sizes other than those mentioned above
are viewed, the operator must be thoroughly familiar with the operation of
the table and the damage that can be done. ',.f certain earlier criteria are not
followed,
The Master Control Console .must be used with the table as all
programming emanates from it, A. brief description of the programming
functions is as follows:
CAUTION: NEVER HAVE THE POWER PLUG CONNECTED TO THE
LIGHT TABLE WITHOUT THE MASTER CONTROL CON-
SOLE BEING CONNECTED! ! !
1, The "Power" switch is used. to turn the table ON and OFF
(#3 Figure 3).
2, The "Bottom Group" switch controls the bottom film trans
porting system (#4 Figure 3).

3, The "Direction" switch controls and indicates the mode of
film. travel (#5 Figure 3),
4, The "Top Group" switch controls the top film transporting
system (#7 Figure 3),
The film transporting mechanism allows the following options:
1. Two rolls of 70m.m or 5" film can be transported in the same
direction,
2. Two rolls of 70m.m or 50? film can be transported in opposite
directions,
3. Transporting the top roll of film. while the bottom roll of film
does not move,
4. Transporting the bottom. roll of film. while the top roll of film
does not move.
Located immediately below the programming switches are another
set of controls for controlling the High=Intensity Tracking Light Sources.
"WHEN FIRST TURNING ON THE HIGH-INTENSITY TRACKING
LIGHT SOURCES, ALLOW 5 MINUTES OF WARM-UP TIME
PRIOR TO OPERATION."
The lower alphabetical character always controls the lower numerical number
on the Selector switch (i, e4 , Selector switch position 1-3, then Dim.m.er A
controls lamp number 1 and Dimmer B controls lamp number 3). When the
Selector switch is positioned on 2, then Dimmer A controls the intensity,
On the vertical portion of the panel the controls for applying braking
action to the supply reels are located. The controls have been labeled to
correspond with their respective functions when the Control Console is facing
the operator and the operator is facing the viewing surface of the Light Table
from the long axis. The control labeled "DIM" is used to vary the intensity
of the large light source. A clockwise rotation increases the lamp intensity.
WHEN FIRST TURNING ON THE TABLE, ALLOW 5 MINUTES OF WARM-UP
TIME PRIOR TO OPERATION,

F. FUSES
There are four electrical fuses protecting the Light Table.
1, The main power fuse us a 3 Amp, 125 V fuse and is located
adjacent to the Power Connector on the back side of the table
housing,
2. There is a 1 /2 Amp, 100 VDC internal line fuse. It is located
on the back of the Control Console adjacent to the Control Cable
connector,
3. The High-Intensity Tracking Light Sources are protected by two
1 Amp, 120 VAC fuses located inside the Control Console and
mounted on a L.ttlefuse terminal board,
CAN: THIS TABLE CONTAINS HIGH VOLTAGE AND
SHOULD BE SERVICED BY QUALIFIED
PERSONNEL ONLY,
G. VIEWING SURFACE SHADES
The Light Table is equipped with shades. The function of the shades
is to mask out the area of light source not being used, When film is viewed
which does not cover the entire viewing surface, the shades (#5 Figure 5) may-
be drawn by loosening the thumb screws (#6 Figure 5) and sliding the shades
to the desired position.
When two rolls of film are viewed, the center strip between the two
rolls of film. may be shaded by using the center shade (#1 Figure 5), This
can be done by loosening the thumb screws (#2 Figure 5) and sliding the shade
to the desired position and then tightening the thumb screws,
H. FILM TRANSPORTING MECHANISM
The film drive mechanism. is hand operated by means of either of
two cranks (#9 Figure 1) on the front side,
Although the film drive mechanism. is hand operated, the clutch-
brake units operate only when power is applied to the desired unit. A clock-
wise rotation of one of the front hand wheels (#9 Figure 1) will transport
film from. left to right when operating with the "DIRECTION" switch in the
~..- same mode, When the "DIRECTION" switch is changed " , the

on the switch, The complete film direction can be reversed by reversing the
direction of the hand crank to counterclockwise.
A two-speed mechanical gear shift (#10 Figure 1) is provided to
switch the film. transporting mechanism. from. low speed to high speed. When
the gear shift rod (#10 Figure 1) is "pulled out, " the film. drive mechanism
is in the "fast" mode.

All microscope adapters are mounted to the carriage assembly by
slipping the adapters over the post on the Microscope Carriage Assembly and
securing the adapter to the Carriage Assembly by tightening hand screw #4
Figure 4.
B. AUXILIARY FILM FLATTENER
An auxiliary plate glass film flattener has been added under the
Microscope Carriage Assembly to remove the camber from the film under
the viewing area of the microscope. The film. should be placed under this
glass flattener and on top of the viewing surface glass.
"WHEN TRANSPORTING FILM, THE PLATE GLASS MUST
BE RAISED OFF THE 3 'i:L M. `P
C. HIGH-INTENSITY TRACKING LIGHT SOURCES
Slaved to the Microscope Carriage Assembly are 3 High-Intensity
Tracking Light Sources. The linkage between the 2 subassemblies is
designed such that the track light sources can be positioned beneath the
separate objectives and/or rhom.biods of a micro stereoscope or beneath the
single objective of a stereom.icroscope in conventional or 900 viewing modes.
