Balancing the Head
If the camera cradle stops
in a horizontal position
(camera pointing directly
forward), the balance is
correct.
Setting the Fore/Aft Balance
Ensure that the head and camera cradle are level before balancing.
The camera and payload should be fitted on the cradle, so that the
load is balanced. This can be achieved by moving the camera
forwards (Fore) or backwards (Aft) on the cradle.
1.
Engage the tilt lock. Loosen the bolts securing the camera to the
cradle just enough to be able to slide the camera and payload
backwards and forwards.
2.
Hold and steady the camera cradle, then disengage the tilt lock.
Carefully release the camera cradle and observe how it moves
and where it stops.
If the camera cradle tilts forward
(points downwards), then the camera
must be moved towards the rear of
the head (aft).
CAUTION!
Risk of damage to equipment. Be prepared to
prevent the camera and cradle from falling away suddenly.
The FH-145/FHR-145 is designed to allow the camera and payload
to swing about its own Centre of Gravity (C of G), as opposed to
balancing with the use of springs or cams. The camera and payload
are mounted onto the camera cradle so the resulting C of G aligns
with the tilt-axis pivot point, providing true balance.
When the head is correctly balanced, the robotic drives will need a
minimum amount of effort to move the head. A correctly balanced
head and payload can be set to any tilt position and the head will
maintain that position ‘hands off’.
