Zero-gauss level
The zero-gauss level offset describes the deviation of an actual output signal from the ideal
output if no magnetic field is present. Thanks to the Set/Reset Pulse and to the magnetic
sensor readout chain, the offset is dynamically cancelled. The Zero-gauss level does not
show any dependency on temperature or power supply.
Zero-rate level
The zero-rate level describes the actual output signal if there is no angular rate present. The
zero-rate level of highly accurate MEMS sensors is, to some extent, a result of stress to the
sensor and therefore the zero-rate level can slightly change after mounting the sensor onto
a printed circuit board or after exposing it to extensive mechanical stress. This value
changes very little over temperature and time.
