3. Counterbalance Control
The counterbalance system was designed to neutralise the
effect of the camera weight when it is tilted. The Compass 15
Fluid Head offers a 4 position counterbalance system which can
be operated via the COUNTERBALANCE SELECTOR
(fig. 2). The COUNTERBALANCE SELECTOR 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 ensure that Counterbalance position 4
is selected.
3.2 Hold the camera and release the TILT LOCK, then gently
tilt the camera from a 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, select Counterbalance
position 3 and recheck, select lower setting again if
necessary. Correct counterbalance setting has been
achieved when minimum effort is required to move the
camera over the entire tilt range.
TIP Fine tuning can be achieved by adjusting the SLIDING
PLATFORM – see step 2.6.
