CAT III - Course Description
The Vibration Analysis Cat III in July is a 5 day course, including a day for review and the exam, and is intended for people who are confident with spectrum analysis but who wish to push on and learn more about signal processing; time waveform and phase analysis; cross-channel testing; machine dynamics; fault correction; and more.
If you wish to truly master vibration analysis and be able to run a successful condition monitoring team, then you are ready for this course.
The course exceeds the ISO 18436-2 Category III standard and meets the ASNT Level III Recommended Practice (for vibration analysis).
The certification exam can be taken after the course. (Note: The ASNT Level III exam can only be administered by the ASNT.)

As a Category III vibration analyst you are expected to be able to diagnose all of the common faults conditions with rolling element bearing machines; have a good understanding of fault conditions associated with sleeve bearing machines; utilise time waveforms, phase readings and enveloping/PeakVue etc. readings to diagnose faults; and understand all condition monitoring technologies, how and when to apply them, and how to combine technologies to get the best results.
You must also understand machine dynamics (natural frequencies, resonance, etc.); how to perform resonance testing; and how to correct resonance problems. You must also understand balancing, alignment, and isolation. You are also, therefore, required to understand all of the single and cross-channel measurement capabilities of your analyser.
And finally, you are also expected to be able to set up the program, run a successful program, and mentor the junior analysts.
You will come away from the course with a solid understanding of:
- How a well designed program, and the reliability centered maintenance approach (with precision balancing, alignment, lubrication and resonance control), will improve the OEE and therefore the bottom line.
- The condition monitoring technologies: acoustic emission, infrared analysis (thermography), oil analysis, wear particle analysis, motor testing – via supplementary training
- How to select the correct measurement location and axis, and collect good, repeatable measurements
- What the Fmax, resolution, averaging and other single-channel and cross-channel analyser settings mean, and how to select the optimum settings for a wide variety of machine types
- How to analyse vibration spectra, time waveforms, envelope (demodulation), and phase measurements
- How to diagnose a wide range of fault conditions: unbalance, eccentricity, misalignment, bent shaft, cocked bearing, looseness, rolling element bearings faults, journal bearing faults, gearbox faults, resonance, and other conditions
- How mass, stiffness and damping affects the natural frequency of a structure
- How to use phase readings, bump tests, impact tests, negative averaging, peakhold averaging, transient (run up and coast down), ODS, and modal analysis to determine natural frequencies and visualize machine movement
- How to set alarm limits manually and with statistics
- How to balance and align a machine, correct a resonance conditions, and employ isolation.
Who should attend?
If you are Category II (or Level II) certified and are ready to take your career and responsibilities to the next step, and you wish to truly master vibration analysis, diagnosis and correction, then this course is idea for you.
You should have over 36 months of experience and a good understanding of fault diagnosis and spectrum analysis. (Note that you require 36 months experience to be certified.)
The RMS / Mobius Institute course and certification program follows the ISO 18436-2:2003 standard and the ASNT Recommended Practice SNT-TC-1A.
What is unique about this course?
RMS / Mobius make it unique. We use 3D animations, Flash simulations, and numerous software simulators that completely demystify vibration analysis. While vibration training courses have traditionally been very theoretical, difficult to understand, (and boring), you will be captivated by the Mobius Training methods, and you will enjoy our practical approach. You will take away skills that you can immediately apply to your job, and you will truly understand what you are doing. When senior vibration analysts attend our classes they often say “if only I could have learned this way when I got started” – well, now you can!
Addition benefits unique to RMS / Mobius Institute courses
- Sitting and watching an instructor can be boring… When the instructor is using modern slides, 3D animations, and incredible simulators, there is no way that you will be bored, however there is nothing like hands-on participation.
Hands-on participation accelerates learning and enjoyment (depends on venue)
- In the RMS courses you can use the simulators, and you can collect readings and study real vibration patterns. There is no doubt that the simulators make it easier to understand the topics we cover – but when you can use them yourself, the learning is further accelerated.
Workbooks provide feedback – do you really understand?
- We also provide quiz questions that help you check if you really did understand the topics, and that you will be able to make the right decisions in the field (and in the exam). Every morning we have a lively discussion as we go through the questions.
Take away more than just knowledge
- We don’t just deliver an excellent course. We provide you with resources that you can use before, during and after the course.
Get started before the course even starts
- Before you even start the course you can visit our Learning Zone Web site to take the self-paced iLearnVibration lessons (and read through the manual). These lessons will help prepare you for the course – you will learn so much more if you go into the course with this knowledge.
Excellent materials that you will treasure forever
- During the course you receive a vibration analysis chart, vibration analysis pocket guide, a vibration reference guide, (a very handy booklet); a mouse pad that is covered with classic spectra representing common fault conditions; access to activity sample questions and answers, and our 400+ page VA Category III manual. This new manual is easy to read, is filled with illustrations, follows the course slides exactly, contains an excellent “Equipment Knowledge” appendix, and can be used as a reference in the future.
Don’t stop learning just because the course ends
- For six months after the course (or longer for a small fee), you can continue to access the iLearnVibration self-paced material on the Web site. If you forget something that you were taught, or you just want a refresher, then just jump on to the site and go through the fully narrated lessons.

Distance learning benefits
If the high cost of travel and accommodation, and the time away from your family and work has stopped you from receiving the training that you need, then you should consider our distance learning courses.
At a time that is convenient to you, and at a pace that works best for you, you can take our lessons and learn in a very similar way to attendees of our classroom courses. Depending upon the course, you can either view fully narrated slides, or you can watch a video of the class in action.
Utilizing the popular iLearnVibration and iLearnAlignment products, we offer distance learning courses where you can view the lessons at your own page, in your own time, and get assistance from an instructor when any questions arise. Of course, you can just buy the products and learn at your own pace without assistance, but you are sure to benefit from interaction with the instructor. In certain courses, you can also interact with other students.
These are not noisy, unprofessional videos taken from actual classrooms, each video was carefully created and edited so that you receive the full benefit. As you can see in this sample, you see the instructor talking and you see the slides (and simulators) being used in high resolution. All you need is a good Internet connection and a good monitor (1024×768 or better) and you will be ready to start learning. You can pause and rewind the video so that you can see and hear the instructor cover the topic again.
In addition to the lessons, hands-on videos are presented where a variety of vibration analyzers are used to perform a range of tests. The analyzers currently include (in alphabetical order) the AzimaDLI DCX, Commtest 4-channel VB-8, Emerson 2120 and 2130, PRUFTECHNIK VibExpert, Rockwell, SKF, and SPM Leonova Infinity. The tests include demonstrations of averaging (linear, rms, and peak hold), bump tests, run up and coast down tests, simple ODS tests, bearing fault detection tests, phase analysis, live spectrum analysis, time waveform analysis, and more.
You can also perform activities defined by the instructor, and take quizzes that will be reviewed by the instructor.
This is a great way to learn. The convenience of learning from home, and the reduced costs associated with travel, meals and accommodation make this a very attractive option – especially while the world’s economy is still recovering.
