Balance mechanism digital display calibration
(Fig 6)
The digital display (11) indicates the setting of the balance mechanism on a scale of 0 (minimum setting)
to 100 (maximum setting). In the unlikely event of this system requiring calibration, proceed as follows:
NOTE: If more than five minutes is allowed to elapse before completion, the system will shut
down and revert to its previous settings.
Level the platform and apply centre lock (4).
Press and hold both buttons (10, 12) until CAL is displayed on the top row of the display.
Push in and turn the balance knob (5) counterclockwise until its minimum end stop is reached, then
turn back two full turns. The bottom row of the display will flash 0.
Press and release the timer button (10). The bottom row of the display will flash 100.
Push in and turn the balance knob (5) clockwise until its maximum end stop is reached, then turn
back two full turns.
Press and release the timer button (10). Calibration is now complete and the display will revert to
the default clock mode.
After calibration, rebalance the head (see Balancing the head on page 12).
Adjustments
To enable the payload to be correctly balanced, the wedge adaptor may require repositioning.
The following adjustments may be necessary after prolonged use:
The platform slide clamp may require adjustment.
The pan and tilt brakes may require adjustment.
Repositioning the wedge adaptor
(Fig 1)
The wedge adaptor (14) is secured by four cap head screws (15) which pass through the wedge adaptor
into the sliding plate (13). The wedge adaptor may be fitted in three positions.
WARNING!
To reposition the wedge adaptor:
Engage the centre lock (see Locking the platform on page 13) and remove the payload.
Hold the body of the wedge adaptor (14) and use a 4 mm hexagon wrench to remove four securing
screws (15).

Overlong screws will prevent the sliding plate from operating. Always use
the screws provided (M6 x 30 mm).
