Leave the camera fixing bolts just loose enough to be able to slide the camera
backwards and forwards on the platform [6].
Mount the lens on the camera (if it was not already installed) and any other ancillary
equipment such as tally lights, viewfinder, and so on.
Balancing the head
When the HS-105 pan/tilt head is correctly balanced the robotic drive will need a minimum
amount of effort to move the head.
Fore and aft balance
When positioning the payload it is important to be aware of the potential danger of an
unbalanced payload falling away suddenly. Balance the payload fore and aft as follows:
Ensure power to the head is switched off and that the camera and all accessories are
fitted.
Hold and steady the platform [6]. Carefully release the platform [6] and observe how it
moves and comes to rest.
If the platform [6] tilts forwards (the lens points downward) then the camera must be
moved towards the rear of the head.
If the platform [6] tilts backwards (the lens points upward) then the camera must be
moved towards the front of the head.
Reposition the camera as required on the platform [6] and repeat step 2 until balance
is achieved. Tighten the camera fixing bolts. When the horizontal balance is correct the
platform [6] comes to rest in a horizontal position.
If there is insufficient movement in the platform slots [7] to achieve horizontal balance,
reposition the mounting plate (supplied with the camera) on the camera as required and
then re-fit the camera to the platform [6].
NOTE: Depending on the camera configuration, it may be necessary to use an
intermediate plate to raise the C of G sufficiently to align with the tilt axis.
Warning!
1. Robotic equipment may move without warning. Switch off the power to
the head before making any adjustments to the head.
2. Risk of finger trap in moving parts. Be prepared to prevent the head
falling away suddenly.
NOTE: It is important that the camera and all accessories (lens, zoom and focus
controls, tally lights, lens drives and so on) are fitted in their operational
position before balancing the head. Any equipment fitted or adjusted later will
unbalance the head.
