Using angle beam transducer and deicphering signals on digital oscilloscope

Hi Friends;
I am using ultrasonic angle transducer for detection of cracks. Me Exciter pulser is in pulse echo mode. I want to know at what pace should I move me transducer so that I get good results. Further more, how one can determine the exact location of cracks by looking at the digital signals in the oscilloscope. How to develop the skill of precision in deciphering signals for cracks.
Cheers
Heather

Heather, you just have to be kidding, right?

*Maximum* scanning speed is usually given in specs as 150mm/sec. Mostly you have to be going much slower than this.
Exact location is calculated using simple trigonometry.
I sincerely hope you're only scanning test pieces as practice for the training course you're going on!

Exertus Dual 120

The Exertus Dual 120 Projector has the ability to accept Iridium 192 sources or Selenium 75 source
...
s. This projector incorporates design and safety features that make it flexible, compact and lightweight. The Projector is lighter than most of its competitors. It incorporates an improved source channel, based on a new helicoidal design, which makes maintenance easier. The helicoidal design also allows smoother movement of the source assembly inside the device, making it easier for the operator and improving safety. The Projector also has a unique safety feature not found in competitive products. The source assembly locking mechanism is triggered by the source holder capsule at the front of the source assembly, thereby always assuring the operator that the source has returned to the safe position. The Exertus Dual 120 is ISO3999:2004 compliant.
