The 2575D pan and tilt head embodies a patented sinusoidal counterbalance
mechanism for true and accurate balance; stepless drag assemblies for ultra-
smooth pan and tilt motions; and an adjustable camera mounting plate.
Counterbalance
The balance mechanism is adjusted by the counterbalance crank on the lower
right of the head. The knob has a folding handle which incorporates a clutch
to prevent inadvertent damage to the balance mechanism by over cranking.
Maximum and minimum payloads that can be balanced are dependent on the
weight of the camera and accessories and on the center of gravity (C of G)
height. The graph below shows the range of loads and C of G heights that
can be maintained in balance. The counterbalance can be adjusted all the
way to zero (no counterbalance) and the head can still be tilted ±90º.

Numeric Display
The numeric display indicates the setting of the counterbalance mechanism
on a scale of 0-99%. Adjust the counterbalance crank clockwise to increase
the counterbalance setting and counter clockwise to reduce it. The display
has a three color coded band offering advance warning of cranking to the end
limits. Green represents the normal operating range, yellow indicates
adjustment within 20-10% from the end limit and red indicates adjustment
within 10-0% from the end limit. When cranking into the red zone be careful to
stop before reaching either “0%” or “99%”.
