18 To balance the camera, proceed as follows:
18.1 Set the head horizontal and engage the tilt brake (14).
18.2 Fit the pan bar or bars (with zoom and focus controls if used) to the head.
18.3 Turn the balance adjustment knob (3) as far as it will go counter-clockwise, then turn it
approximately 5 revolutions in a clockwise direction to apply some counter-balance.
18.4 Assemble the camera and ancillary equipment on the slide plate and fit the slide plate to the
head.
18.5 Release the slide plate lock (10) and position the slide plate to bring the C of G of the load
approximately over the head tilt axis. Re-engage the slide plate lock but do not overtighten.
18.6 Release the tilt brake (14). Turn the balance knob (3) counter-clockwise until the head falls away
from horizontal under the weight of the load.
18.7 Adjust the fore-and-aft position of the slide plate until the load will balance when the head is
horizontal. Apply the slide plate lock (10).
18.8 Turn the balance knob (3) clockwise until the load does not fall away when the head is tilted and
released.
18.9 Repeat the adjustment steps until the load will remain set at any angle within the range of tilt
defined by the graph (Fig 2.1). Provided the load is within the recommended range, the correctly
balanced assembly will retain any degree of tilt within this range with the tilt brake released and the tilt
drag set to zero.
18.10 Apply the tilt brake (14).
Operation
Adjusting pan bars
19 With the pan brake and tilt brake applied, adjust the position of the pan bar to suit the operator's
requirements by slackening the quadrant clamp knob and moving the pan bar and quadrant to the desired
position. Tighten the clamp knob.
20 Adjust the length of the telescopic pan bar by releasing the pan bar clamp knob and sliding the bar in or
out. Tighten the clamp knob.
Setting pan and tilt drag
21 Drag setting is entirely a matter of operator preference, and does not affect the ability to perform a whip
pan. Set the pan and tilt drag as follows:
21.1 Release the pan and tilt brakes (12)(14).
NOTE: Adjusting the position or length of the pan bars may necessitate fine adjustment in the
fore and aft position of the camera and the balance.
