# When the response to '''Z''' has been minimized, or if you seem to be unable to reduce the response at all, disable the BK output to '''Z''' and apply a modulation signal to '''X'''. Use the DC Z coils to minimize the magnetometer's response to the '''X''' signal.
# '''Nulling notes'''
## During the above two steps, the DC value of the magnetometer signal will likely swing wildly. Use the '''Y''' current supply to attempt to keep the DC value close to zero. Actually, it's a decent idea to keep sweeping the Y field anyway...as the X and Z fields get closer to zero, the dispersive shape when scanning the y field should become more and more apparent.
## It is possble for the response to X and Z fields to decrease even if the fields
