4. Hang the weight from the clockwise (right) pin and level the calibration beam.
Note:
5. Adjust the CW Calibration trim pot so that the torque reading equals the weight times the
distance.
Note:
6. Transfer the weight to the counterclockwise (left) pin and level the dynamometer.
7. Adjust the CCW Calibration trim pot so that the torque reading equals the weight times the
distance. See Note in step #5.
8. Remove the weight from the calibration beam.

To hang bottleneck weights, Magtrol recommends using only
lightweight (but strong) line. Simply fashion a loop and attach it
to the weight.

If using Magtrol CB Calibration Beams in conjunction with
WT Calibration Weights, simply calibrate to the full scale
torque listed in the table in Section 6.1 – Calibration Beams and
Weights.
