The conditions for the subsequent data are defined in Table 3-2. Data was collected through the Texas Instruments Magnetic Sense Simulator (TIMSS) tool and post processed in excel. With mechanical assembly, there is the possibility that the sensing device can be offset from the intended location, the magnet tilted, or the magnet can not be correctly centered on the axis of rotation. Consequently, multiple separate tests were performed to see the impact of each of these possible error sources.
All parameters in Table 3-2 correspond to input parameters available in the TIMSS tool in Table 3-2.
