Video Testing Procedures:
A. Locate the video test equipment, at a point where
the video display and character to be tested, can
be viewed simultaneously.
1. Connect the cable from the audio output #2, on
the Tape Deck, to the tape select box, (Front
Panel) input channel #3 or #4.
2. The correct input channel is determined by
selecting which character is to be
stimulated, channel #3 is the top drawer and
channel #4 is the bottom drawer. (see Bit,
Valve and Movement Charts, Pages 1-011 thru
1-014)
3. Power up the video tape deck.
4. Load the tape and rewind it completely.
5. Set the unit counter to zero.
B. Play the tape and follow the adjustment
procedures described below. View the tape long
enough to correctly determine that the movement
is truly out of adjustment. (Do Not adjust the
Flow Control unless you are sure the movement
needs adjusting) The video display and character
must be synchronized exactly. If a movement is in
question:
1. Isolate the valve in the valve bank that
operates the movement in question. (see "Bit,
Valve and Movement Charts", Pages 1-011 thru
1-014) Manually operate the valve, by pressing
the white manual override button on the
valve's solenoid.
2. Observe the movement by operating it manually.
Look for a smooth operation of the movement in
question, check for Cosmetic parts that are
binding, if problems are present refer to
PART 2 Mechanical Trouble Shooting.
c. After determining that the movement truly does
need adjusting, turn the Flow Control Adjustment
screw. Remember the air coming out of the
cylinder is what you are adjusting. (For a
explanation of the air system see Pages 3-002
thru 3-030, The Air System.
