1. 1) For absolute outputs, a practical speed limit is 2345 mm/s. At higher speeds, input signal cancellation will occur and the detected field
decreases due to the internal front-end. Significant signal change is indicated by the status bits.
2) With increasing speed, the distance between two samples increases. The travelling distance between two subsequent samples can
be calculated as:
v
fs
where:
sampling_distance = travelling distance between samples (in mm)
v = travelling speed (in mm/sec)
fs = sampling rate in Hz (see Table 9)
