OPERATION
1.
Y-8 Model Only: Charge battery before use.
2.
Connect yoke to power supply / battery pack.
3.
Select AC or DC operating mode using switch on back of yoke.
WARNING: Do not operate selector switch while yoke is energized.
4.
Position yoke legs at right angles to the direction of suspected discontinuities. Adjust legs
as needed for best contact with surface.
5.
Depress trigger to energize yoke. Apply magnetic particles to area between legs.
a.
If using dry powder, blow off excess while yoke is energized to reveal indications.
b.
If using fluorescent particles, view surface with UV-A in darkened environment to
reveal indications.
6.
Evaluate indications for size, shape, and relevant location.
7.
Reposition yoke legs at 90-degrees to previous position and repeat steps 4-5 to reveal
indications in all directions.
8.
Y-6 and Y-7 Models Only: Demagnetize by energizing yoke then slowly withdrawing it from
the surface, up to 18 in / 45 cm distance. NOTE: Use AC mode for demagnetization.
