Checking Camera Balance; Pan And Tilt Brakes; Pan And Tilt Drag - Vinten PRO-6 HDV System Guide De L'utilisateur

Attach the slide plate (17) to the camera or camera mounting plate under the approximate centre of the
camera's weight using the fixing screw (6) or (19) and locating pin (5) (if appropriate).
Set the platform level and apply both the pan (15) and tilt brakes (4).
Lower the camera onto the platform (Fig 4) ensuring that the edge of the slide plate opposite the slide clamp
engages first, and then push downward so the slide clamp 'snaps' into position.
Tighten the slide plate clamp (2).

Checking camera balance

HDV
The PRO-6 head provides a selectable balance range, set for payloads of 2.5kg (5.5lb) to 6kg (13.2lb)
at a centre of gravity (C of G) height of 5.5cm (2.2in.). The graph (Fig 5) shows the relationship between C
of G height and payload for optimum performance.
The balance selector (8) allows four balance levels to be utilized. Level '0' offers free rotation of the tilt axis
with no counter-balance engagement. Levels '1' to '3' offer gradually increasing balance capacity (Fig 5).
Check the camera balance as follows, remembering to ensure that the pan bar(s) and any ancillary equip-
ment have been fitted:
NOTE: Be prepared to prevent the head falling away suddenly.
Reduce tilt drag (3) to level '1'.
NOTE: When changed, the selected balance level (8) engages as the platform moves through
the horizontal position.
Release the tilt brake (4).
Position the camera correctly on the head by releasing the slide plate clamp (2) and sliding the camera
backwards or forward until it balances horizontally. Apply the slide plate clamp (2).
Using the pan bar (9), tilt the head backwards and forwards. If the head tends to fall away, select a higher
balance level (8). If the head tends to spring back, select a lower balance level (8).

Pan and tilt brakes

Brakes on each axis allow the head to be locked at any chosen position. The operating lever for the pan
brake (15) is at the rear of the head. The tilt brake (4) is operated by a lever on the left-hand side of the
head.
To apply the pan brake, turn the lever (15) fully clockwise. To release the brake, turn the lever counter-
clockwise.
To apply the tilt brake, turn the lever (4) fully counterclockwise. To release the brake, turn the lever clock-
wise.
WARNING! When the brakes are not in use, always ensure they are fully released.
DO NOT use the brakes to supplement drag.

Pan and tilt drag

Both the pan and tilt mechanisms incorporate a fluid drag system to ensure smooth movement of the cam-
era about these axes.
