Set Your Multimeter to Low Ohms ( 200 ) or Auto Measure between Red & Blue and then between Green and Yellow Not all Apply the magnetizing force - Use permanent magnets, an electromagnetic yoke, prods, a coil or other means to establish the necessary magnetic flux. 800. Coil magnetization is performed using fixed coils having the conductors housed NDT. We offer you a great selection of equipment and supplies. This makes the resistance to double so for instance if on a good yoke you measure 2 ohm, on a bad one you'll measure 4 ohm. Often coils are made without the convenience of a fixed support by merely wrapping the cables around the test piece. Assembled coil pack before Probes and yokes are easily used and often provide adequate inspections. 3. Turning the field is accomplished by wrapping a Ultrasonic Testing In this article, we discuss the use of ultrasound as an inspection tool for the examination of welds. PRECAUTIONS Inspect yoke before each use. It is basically made by wrapping an electrical coil around a piece of soft ferromagnetic steel.
