8. TapSetnexttoPitch,setthevaluetohalfthedisplayedvalues,andtapSetagain
(i.e.‐5.3/2=‐2.65and‐2.8/2=‐1.4)(Figure29);repeatfortheRollvalue,andthentapOK.

9. CheckthePitchandRollvaluesinbothpositions.Thetwovaluesforeachpositionshouldbe
equal,butonewillbepositiveandtheothernegative. 
Oncethebodysensorrollvalueiscalibrated,recordthevaluesomewherethatisaccessible
fortheremainderofthecalibrationprocess.Aslongasthebodypitchandrolldoesnot
change,thisvaluecanbeenteredforallothersensorrollvalues.Ifthebodypitchandroll
valueschange(i.e.themachinetracksaremovedorthemachineisrotated),thenewroll
valuemustbereferenced.
