Adjusting centering
The
zeroG
arm is designed to move almost effortlessly, so it is very sensitive to gravity.
You can adjust the mounting interface block so the arm comes to rest centered or to the
side only as far as you want it to. This is a preliminary rather than a precise or final ad-
justment. The adjustment will have to be refined when the payload is attached.
•
Two of the three types of mounting interface blocks are adjustable. The static block
is not adjustable.
•
Pitch
adjustment moves the bracket—where the arm attaches—up and down, in a
head-nodding motion.
•
Roll
adjustment rotates the bracket, as viewed from the front.
The dynamic and preset mounting interface blocks have different adjustment mechan-
isms, but the process of adjustment is the same. Repeat these steps until the rest posi-
tion is centered.
1.
Hold the arm pointed toward the work area and without letting go completely, let
it move freely.
2.
If the arm drifts consistently to one side, adjust the pitch down and the roll away
from the direction of drift.
3.
If the arm drifts to either side, adjust the pitch down.
Adjust a dynamic mounting interface block
•
Adjust roll by turning the crank on the side of the
mounting interface block. Cranking clockwise rolls
the bracket counterclockwise.
•
Adjust pitch by turning the crank on the top of the
mounting interface block. Cranking clockwise
pitches the bracket down.
