Probe correction is ignored in that it is assumed that the probe measures the exact values of the field on the scan plane. Two fundamentally different approaches are used in deriving three sets of formulas that give the fields in the source …
WebFeb 13, 2024 · This allows the device to measure coefficients of friction for steering angle positions from 0 to 160 mrad (subject to the vertical load). This measurement is easily transferred to creepage values from 0% to 16% based on the rule that creepage of 1% equals an angle of attack of 10 mrad.
