tions

7.2.3.1 Select AC on the AC/DC power switch.

7.2.3.2 Place probe/yoke on the part so that the probe/yoke is parallel with the long axis of the shock strut.

legs a minimum of 1/4 inch above the weep hole maintaining contact with the shock strut.

threaded ring. Improper placement of legs will generate an insuffi-

cient magnetic field.

the media momentarily before removing the current. Current should be applied for no more than five seconds.

Verify magnetic field with field indicator.
