Miller DS20 - Manual (Page 5)

The counterbalance system was designed to neutralise the effect
of the camera weight when it is tilted. The DS10 & DS20 Fluid
Head offers a 2 position counterbalance system which can be
operated via the COUNTERBALANCE SELECTOR (Fig. 2 & 3). The
DS5 Fluid Head has a single position Counterbalance system and
is preset. 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 2 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 select
Counterbalance position
1. 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 2.5.
The DS5/DS10/DS20 Fluid Head offers high
capacity calliper disc brake system to hold
the Fluid Head in a fixed pan and/or tilt position.
Camera position will not change when applying or
releasing the Pan / Tilt locks.
WARNING: Do not pan or tilt the Fluid Head whilst the PAN or
the TILT LOCK is partially applied.
