5. Turn the current dial to 2.
6. Check for magnetizing current.
7. Make sure there is no connection between the cables of the contacts output.
8. Depress the MAG push-button while observing digital ammeter. The current assurance light should not
light. If there is any indication of current on the ammeter, or the current assurance light lights, an
electrical short exists. For correction action, refer to Section 5 for Troubleshooting.
9. Connect a suitable cable (load) between the output terminals of the activated output.
10. Depress the MAG push-button while observing the digital ammeter. The magnetizing current flowing
through the load should appear on the digital ammeter. The green current assurance light on the
ammeter should light indicating current flow.
NOTE: To ensure reliable processing of parts, all above conditions must be met. For corrective action, refer
to Section 5 Troubleshooting.

SET UP
WARNING:
Heavy materials may cause severe damage or injury if dropped; always make sure part is
stabilized before processing for inspection.
Normal Piece Set Up
All controls and indicators are illustrated in Figures 2-9.
1. Contact: Align cables and part so that current will flow parallel to direction of expected flow. This places
magnetic field at right angles to flaw and provides best indications. Apply fluid or powder (continuous
method). Press MAG button. Apply fluid or powder (residual method).
2. Coil or Cable Wrap: Align part and cables so that field is perpendicular to direction of expected flaw.
Apply fluid or powder (continuous method). Press MAG button. Apply fluid or powder (residual
method).
Remote Operation Set-up
For remote operation, connect remote cables. Use optional clamps, prods, or cable wraps to magnetize parts
for inspection.
Central Conductor Set-up
If parts are hollow, tubular, ring-like, or have holes, it is generally better to magnetize them using a central
conductor rather than passing current directly through them. This method also reveals defects on the inside
diameter of the part. Circular Magnetization is accomplished by passing current through the central conductor.
