Test Attachments
There is little calibration required to set up fly’s and jibs. The most likely requirement is for a deflection
correction. The deflection correction may be applied to each attachment by calibrating with the bdc
command. Do not calibrate bdc unless unloaded tests are complete and satisfactory, and the main boom
radius accuracy is correct.
The angular offset of the fly is normally the dimension that requires change in the capacity chip during
testing. Since all fly’s fit to the boom head using the same physical attachments, the offset angle of all
fly’s with the same offset may be modified at the same time.
Test the longest fly at all of it’s offsets before making corrections to the capacity chip and continuing with
other attachment testing.
Data collected from the main boom calibrations may be added to the capacity chip at this time also.
Test sequence
Start testing with the longest attachment at the straightest offset angle.
It is a good idea to check the length and vertical offset dimensions of the attachment with a tape before
commencing tests. If necessary correct the values of these in the capacity chip.
The following tests should be done on each attachment:
