Introduction The Vision 250 pan and tilt head embodies an adjustable spring counterbalancing mechanism, thin film (TF) drag assemblies for pan and tilt motions and an adjustable camera mounting plate. The balance system is easily adjusted by a knob (2) on the rear of the head. Maximum and minimum payloads that can be balanced, and tilt ranges, are depend-ent on the weight of the camera and accessories and on the centre of gravity (C of G) height.
A digital display (6) indicates the setting of the balance mechanism on a scale of 00 - HI. The display is illuminated by pressing the switch (9) and extinguishes automatically approximately 15 seconds after adjustments are complete. The same switch also illuminates the level bubble (4) and the scales of the pan and tilt drag knobs (19)(10). A sensor (5) automatically compensates for ambient light levels and dims the display.
Operation Installing the head The Vision 250 head is supplied with a dual 100/150 mm ball base and is designed for installation on a compatible Vinten Vision tripod. The head is also available with a flat base, with `Quickfix' and standard four-hole fixing. Adaptors are available which enable the heads to be installed on tripods or pedestals fitted with other mountings. These are listed under ‘Optional Accessories’.
Mounting the camera (optional Quickfit adaptor) If not already attached, secure the Quickfit adaptor (23) to the slide plate (14) with the two screws provided (1). Free the Quickfit wedge (22) from the adaptor by simultaneously pushing in the safety catch (25) and operating the wedge release (24). Fit the Quickfit wedge (22) to the camera with the two screws provided (21). Set the platform level and engage the centre lock (3). Insert the forward end of the wedge into the forward end of the adaptor.
Balancing the head Balancing the Vision 250 head achieves two objectives. Firstly, when a head is correctly balanced the operator will need a minimum amount of even effort to move the head. Secondly, once balanced, the head and its payload can be set to any tilt position and the head will maintain this position with ‘hands off’. Prior to balancing the head ensure that the pan bars and any ancillary equipment have been fitted in order to prevent upsetting the balance once it has been achieved.

Locking the platform The centre lock mechanism is operated by a slider on the rear of the head. To engage the lock, hold the platform in the horizontal position and push the slider (3) to the left. To release the centre lock, push the slider (3) to the right. Pan and tilt brakes Friction brakes on each axis allow the head to be locked at any chosen position. The operating levers for the pan brake (11) and tilt brake (12) are fitted on the left-hand side of the head.
Servicing Routine maintenance Replace the balance mechanism digital display battery yearly. During use, check the following: Check the effectiveness of the pan and tilt brakes. Reset as necessary. Check the operation of the balance mechanism digital display and the illumination of the level bubble and drag knobs. Replace battery if necessary. No further routine maintenance is required. Cleaning During indoor use, the only cleaning required should be a regular wipe over with a lint-free cloth.
Install the battery (16.2) in the battery compartment, ensuring that the wiring is neatly stowed. Refit the battery cover (16). Press the switch (9) and ensure that the balance mechanism digital display (6) is lit for approximately 15 seconds. Put a finger over the light sensor (5) and press the switch (9). Ensure that the level bubble (4) and drag knob scales (10)(19) are lit. (9) (16.2) (16.1) (16) BATTERY TYPE 9v, 6LR61 (PP3, 6AM6, MN1604, E-BLOCK) Vinten Part No.
Balance mechanism digital display calibration The digital display (6) indicates setting of the balance mechanism on a scale of 00 (minimum setting) to HI (maximum setting). In the unlikely event of this system requiring calibration, proceed as follows: Level the platform and apply centre lock (3). Turn the balance knob (2) fully clockwise to its maximum stop. NOTE: If more than 15 seconds is allowed to elapse between steps, the system will shut down and revert to its previous settings.
Converting the base Spares kits are available to convert the head from ball base to flat base versions and vice versa. Kit 3525-900SP comprises a ball base, bowl clamp and fixing hardware; while kit 3525-901SP has a flat base, mounting bolts, and washers, a spanner and fixing hardware. To change the base: Remove the camera from the head. On the base, remove four screws (17.1) and separate the base (17) from the head. Position the replacement base on the head and secure with four screws (17.
