Install the calibration arm and weights using the bolts at the end of the calibration
arm.
Note:
If you do not have enough room to use the bolt pattern closest to the end of
the calibration arm, use the bolt pattern in the center of the arm.
9a
Secure the calibration arm to the eddy current brake by tightening the bolt
using the handle.

Gently place the weights on the calibration arm.
Note:
Verify the calibration arm is not contacting the cover.
CAUTION
The calibration weights are very heavy. The weights must be set on the
arm gently to avoid damaging the load cell.
