OMA - Measure Deviations and Torsion - Helmholtz Coordinates

Print out of the OMA torsion test using Helmholtz coordinates at 25 degrees showing measurements of the deviations in all the 9 testing points. Torsion and deviation measurements can be carried out at a choice of 20, 25 and 30 degrees away from the primary position.
