If not already done, apply both pan brake
(10)
and tilt brake
(12)
by turning the levers in a
clockwise direction.
Lower the camera onto the camera mounting platform
(Fig. 5)
ensuring that the edge of the
camera slide plate
(16)
opposite the slide clamp
(13)
engages first, and then push
downward until the slide clamp ‘snaps’ into position.
Using the pan bar
(5)
to steady the camera, tighten the slide plate clamp
(13)
in a clockwise
direction to secure the camera in position.
Checking camera balance
A perfectly balanced head allows operators to control camera movement with the minimal amount
of effort. Once balanced, the head and its payload can be set to any tilt position and remain at that
position, allowing operators work hands-free.
Balance graphs (
Fig. 8
,
Fig. 9
,
Fig. 10
and
Fig. 11
) illustrate the relationship between load and
Centre of Gravity (C of G) height for each Vision AS pan and tilt head. The balance graphs can
be used to ascertain the suitability of the head for any given combination of camera, lens and ac-
cessories. The shaded area of graph corresponds to those load/C of G combinations that can be
balanced over the full tilt range. The areas to the right indicate the progressively reducing tilt range
with greater load and higher C of G. Where a load/C of G combination falls outside of the graph it
will be necessary to increase or decrease the weight or the C of G height to enable the head to
balance the load.
Before balancing the head, ensure that the camera and lens, pan bar(s) and all ancillary equip-
ment has been fitted. The head must be balanced whenever the camera and/or lens is changed,
or when ancillary equipment is added or removed.
CAUTION! DO NOT use force on the brake levers. Hand tighten only.
