4 GTR9-6-24 Basic Information  Start of analysing the Round Robin tests with the so called Masterlegs which were carried out from August 2012 to January 2013 world wide  In this presentation only the tests performed by Bertrandt are analysed / included  The objective is to show the behavior of the calibration results during 2 weeks testing Durabilitystudy SN03 at Bertrandt Laboratory, J.C. Kolb 3

5 GTR9-6-24 Database  Schedule: 15.10.2012 – 26.10.2012  Masterleg: SN03  Calibration: Bertrandt  Testing: Bertrandt, Audi  Number of tests:  Pendulum: 12 tests  Inverse: 10 tests  Other tests: 32 tests 54 tests  Calibration corridors: made up in Sept 2012, shown on following slide Durabilitystudy SN03 at Bertrandt Laboratory, J.C.
