Dynamometer Tilt: Permits rotation of the
dynamometer on a vertical plane allowing the shaft
axis to tilt upward or downward from the horizontal
position. To tilt the dynamometer, support the
dynamometer with one hand. With the other hand,
loosen the Tilt Knob in a counterclockwise direction.
Gently push or pull the dynamometer to the desired
position. Tighten the knob firmly in a clockwise
direction, and ensure that the dynamometer teeth
are engaged, to secure the dynamometer in place.
Use the Tilt Scale (located on the yoke) to note the
new dynamometer tilt position. Use the Tilt Key
(located directly beneath the Tilt Scale for a quick
reference during patient set-up.)
Dynamometer Height: The dynamometer can be raised or
lowered over a range of 14” (35.56cm). Loosen the Height
Handle by turning it counterclockwise and
simply apply hand
pressure to the top or underside of the dynamometer to
respectively raise or lower it. Retighten the handle to lock the
dynamometer in position. Use the Height Scale, located on the
mounting post, to
note the new dynamometer height.
NOTE: The weight of the dynamometer is counterbalanced by a pneumatic
assembly in the mounting post. When the locking handle is loosened, the dynamometer may
tend to gently rise or fall, depending on the weight of attachments affixed to the shaft. After
proper height is established, always secure the locking handle.
Dynamometer Travel (850-000, 840-000): The Foot Pedals allow the dynamometer to move
along the travel in a horizontal plane left or right of the positioning chair. To move the
dynamometer, press down on either foot pedal and slide the dynamometer to the desired
location. Release the foot pedal to lock the dynamometer in place. To ensure stability, check
that the dynamometer is fully locked in a detent (i.e., try to shake the dynamometer). Use the
Position Scale on the travel to note position.
Rotate Clockwise/Counterclockwise: The Rotate buttons atop the dynamometer allow the
shaft to be moved by pressing (and holding) the Rotate button corresponding to the direction
the shaft must turn. This function of the Rotate buttons has no effect on the range of motion
limits previously established in Setup Mode.
