Balancing Pitch axis
The goal is to align the camera's (vertical) CoG to coincide with the Pitch-axis line running through the center of
the roll-motor shaft's centerline. When this is achieved, the camera will remain stable and motionless when lens is
moved up-and-down to any angle above or below the horizontal plane (tray being parallel to ground) position.
Whenever camera lens is moved up or down from the horizontal position, if the lens tends to move faster in the
direction it is being moved to, then the camera CoG is too high above the pitch-axis centerline. When moved up and
down, if lens always returns to the horizontal position, then the CoG is too low below the pitch-axis centerline.
To check the pitch balance, move the camera lens gradually up and down from the horizontal position (parallel
with ground) — from pointing lens barrel slightly upward, to pointing straight at the ground. When at a certain attitude
(angle) pointing downward, the lens sinks downward faster, then the CoG is too high above the pitch-axis (top-heavy
condition). So the front panel must be moved downward (as the lock screws relocate to higher positions in the vertical
adjustment tracks).
Conversely, when lens barrel is moved up or down, if the lens always returns to the horizontal position (parallel to
ground), then the camera's CoG is too low (below the pitch axis centerline). In which case, the front panel must be
moved upward in order to raise the camera's CoG to coincide with the pitch-axis centerline.
