NOTE
: LATER AFTER YOU ADJUST THE
VERTICAL BALANCE OF THE HD-2000
YOU WILL HAVE TO GO BACK AND
READJUST THE HORIZONTAL BALANCE
AGAIN IN ORDER TO OBTAIN A TRUE
FINE
BALANCE
OF
THE
WHOLE
SYSTEM.
BALANCING THE VERTICAL AXIS
Now that your HD-2000 is horizontally
balanced, it’s vertical axis can now be tested
and properly balanced. The objective in
obtaining correct vertical balance of the HD-
2000 is to allow the Camera and HD-2000 to
remain level during operation, given you are
not applying either a pan, tilt, or roll type of
hand pressure to the HD-2000, and most
importantly that the HD-2000’s CENTRAL
POST remains vertical even if you are
walking, running, or turning while the HD-
2000 is in operation. In other words, if the HD-
2000 is vertically balanced correctly then the
Camera will remain level, and the CENTRAL
POST will remain vertical unless you
intentionally position the HD-2000 otherwise.
If the HD-2000 is not vertically balanced
properly, then it will swing about and
pendulum when you walk, run or turn.
Again, if the vertical balance is set correctly you
will be able to move about quickly, as well as start
or stop moving suddenly, and still have the central
support post remain vertical. To adjust the HD-
2000’s vertical balance you can either add, or
subtract COUNTER WEIGHTS from the BASE
PLATFORM, or telescope the BASE PLATFORM
in or out. After you have approximately the right
amount of WEIGHT on the BASE, you can then
fine tune the VERTICAL BALANCE by using the
TELESCOPING POST.

Test” (see next page).
