Bias variation after calibration, bias is
continuously estimated by XKF3i. The
estimated biases are cleared on a device
reset (including power cycle). Not applicable
for FMT-1010 modules.

applicable for FMT1010 modules.
Hz
This is the resonating frequency of the mass
kHz in the gyro. The higher the frequency, the
higher the accuracy.
