Patent ID: 7768250

Claim:
A method for locating a device and a probe assembly relative to a work piece, where the device and the probe assembly are positioned on different sides of the work piece, and the probe assembly is affected by a magnetic field generated by the device, the method comprising: mounting said probe assembly on a platform that is moveable relative to a mounting structure, with the mounting structure being fixable to the work piece; providing said mounting structure with a manually engageable first axis adjustment control for enabling a user to move said platform along a first axis, and a manually engageable second axis adjustment for enabling the user to move said platform along a second axis perpendicular to said first axis; placing said device on a first side of the work piece; producing a field with said device through said work piece; placing said platform with said probe assembly mounted on said platform adjacent a second side of said work piece; using information from said probe assembly to enable the user to adjust said first and second axis adjustment controls to move the probe assembly along said first and second axes to substantially determine a position of the device; determining a location of a center field axis of said magnetic field with said probe assembly; and confirming said center field axis to a user.
