Abstract:
1. Method of adjusting a single-axis, fluxgate magnetometer apparatus, said method comprising the steps of: winding a toroidal core with a predetermined number of turns of an excitation coil to form an excitation subassembly; winding a coil form with a predetermined number of turns of a pick up coil around a hollow chamber thereof to form a pick up subassembly; disposing said excitation subassembly into said hollow chamber of said coil form; applying an excitation signal to said excitation coil while disposed in said hollow chamber; monitoring a signal waveform of the pick up coil responsive to said excited excitation coil; adjusting the position of the excitation subassembly in said hollow chamber to effect a desired signal waveform of the pick up coil; and securing the excitation subassembly in said hollow chamber at said position that provides said desired signal waveform.
