Operating Instructions
5. Counterbalance Control
The counterbalance system was designed to neutralise the
effect of the camera weight when it is tilted. The Arrow
fluid head offers a 16 position counterbalance system which
is operated with the CB SELECTOR KNOB and the CB PLUS
SELECTOR KNOB.
The system was designed for an efficient and ergonomic
control of the counterbalance mechanism which delivers a
wide payload range capacity.
The counterbalance selector knob and the CB PLUS
SELECTOR KNOB must be operated when the SLIDING
PLATFORM is in a horizontal position.
After changing the counterbalance setting it may be
necessary to tilt the camera back and forth to ensure that the
CB spring has engaged. The camera must be held securely
while changing the counterbalance setting.
3.1 For safety select counterbalance position 16, being
the orange coloured marker on the CB SELECTOR KNOB
pointing to position 16 and the CB PLUS SELECTOR
KNOB displaying an orange marker.
3.2 Hold the camera and release the TILT LOCK, then gently
tilt the camera from the horizontal position forward
then backward and observe its response. If the camera
'springs back' to the horizontal position then a lower
counterbalance setting is required, rotate the CB
SELECTOR KNOB clockwise to a lower position and
recheck, select lower setting again if necessary.
3.3 Finer adjustments can be made by toggling the CB PLUS
SELECTOR KNOB (fig. 10).
3.4 Correct counterbalance setting has been achieved when
minimum effort is required to move the camera over the
entire tilt range.
