VA CAT-IV with Community-based Support and Personal Mentoring
CAT IV - Public, Onsite & Online
The Vibration Analysis Cat IV is a 5 day course, including a day for review and the exam. The course exceeds the ISO 18436-2 Category IV standard and meets the ASNT Level IV Recommended Practice (for vibration analysis). The certification exam can be taken after the course. (Note: The ASNT Level IV exam can only be administered by the ASNT.)
Part 1 – Distance learning
Part 2 – Public classroom
The Category IV examination will be offered on the fifth day. The exam consists of 60 questions which must be completed in five hours. In order to be certified the candidate must have completed parts one and two of this course, or provide evidence of equivalent training, hold Category III certification and provide verifiable evidence of 60 months experience.
Who should attend?
If you are Category III (or Level III) 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 ideal for you.
You should have over 30 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!
Course Description - Part 1
Master Vibration Analyst (CAT-IV)
Venue: Distance Learning
Duration: 4 days (equivalent)
Continuing Education Units (CEUs): 4
Part One of the course will be delivered via distance learning; access to a Web site will be required however a computer-based version will be available at an extra cost. The course will be taught by Jason Tranter, founder of Mobius Institute. Quizzes will be performed during the course in order to gauge comprehension.
The primary focus of this course is advanced signal processing, cross channel measurements, dynamics (mass/stiffness/damping, natural frequencies, modes), resonance testing (run-up/coast down tests, impact tests, ODS, modal analysis), and corrective action (flow control, resonance correction, isolation and damping). This course will take a practical approach to these subjects. Animations and software simulations will be used to make these topics easier to understand. Mathematics and theoretical derivations will be kept to an absolute minimum.
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.
- Advanced signal processing
- Cross channel measurements
- Dynamics (mass/stiffness/damping, natural frequencies, modes)
- Resonance testing (run-up/coast down tests, impact tests, ODS, modal analysis)
- Corrective action (flow control, resonance correction, isolation and damping)
- Proximity probe and casing measurements
- Orbit and centerline plot analysis
- Rotor dynamics (natural frequencies, modelling)
- Journal bearings (design, fluid film instabilities)
- Flexible rotor balancing
- Torsional vibration
The Category IV vibration analyst will:
- Apply vibration theory and techniques, including measurement and interpretation of multi-channel spectral results such as frequency response functions, phase and coherence
- Be able to understand and perform signal analysis, including understanding of frequency and time domain processing, including orbits and their limitations
- Be able to determine the natural frequencies, mode shapes and damping of systems, components and assemblies
- Be able to determine and assess the operating deflection shapes of machines and connected structures and recommend means for correction
- Be able to use generally recognized advanced techniques for vibration analysis, parameter identification, and fault diagnosis
- Be able to apply the basic principles of rotor-bearing dynamics to vibration diagnosis
- Extend their knowledge of advanced two-plane influence coefficient or static and couple balancing theory and apply this to large, flexible rotor machines
- Use their understanding of the effect of corrective actions such as component change or repair, isolation, damping, change of stiffness and change of mass, and therefore make recommendations of the actions to take
- Be able to interpret and evaluate codes of practice and specifications published in International Standards and other documents, as they apply to balancing, alarm limits, condition monitoring programs and more
- Be able to recognize vibration caused by gas pulsation in machines, such as reciprocating machines and screw compressors, be able to measure the necessary parameters, and recommend means for correction
- Be able to recommend corrective actions for resilient mounting and other holding-down and foundation problems
- Be able to direct and audit condition monitoring strategies

Course description – Part 2
Master Vibration Analyst (CAT-IV)
Venue: Live Classroom
Duration: 4 days
Continuing Education Units (CEUs): 4
Examination: Provided on the 5th day
This four-day course will be delivered in a classroom environment. Quizzes will be performed during the course in order to gauge comprehension.
The primary focus of this course is the measurement, analysis, dynamics, and balancing of turbomachinery. Topics will include proximity probe and casing measurements, orbit and centerline plot analysis, rotor dynamics (natural frequencies, modeling), journal bearings (design, fluid film instabilities), and flexible rotor balancing. The course will also cover torsional vibration.
Note that this course is designed for people who have come up through the Category I, II, III development process; it is not necessary to have a degree in advanced mechanical engineering or dynamics – we will take a very practical approach. Utilizing advanced 3D animations and software simulations, topics that were possibly beyond the reach of many vibration analysts will be far easier to understand. The aim is to provide the level of knowledge that enables the vibration analyst to understand these topics to a high degree, with the expectation that if advanced analysis, design modification or modeling is required, a specialist in those areas will be called-in.
Day One & Two
We will focus on advanced signal processing, structural dynamics, corrective action (isolation, resonance correction, etc.), ODS, and modal analysis. Along with the topic revision we will go through the worked examples and students will be given poll questions to test their knowledge.
Day Three & Four
We will focus on proximity probe measurements, conventions, orbits, centerline plots, journal bearings, rotordynamics, diagnosing common faults associated with journal bearings and turbo-machinery, and flexible rotor balancing. Once again, along with the topic revision we will go through the worked examples and students will be given poll questions to test their knowledge.
Day Five (Optional Certification Exam)
The Category IV examination will be offered on the fifth day. The exam consists of 60 questions which must be completed in five hours.
60 months of practical vibration analysis work experience (must be verified), CAT-III certification by Mobius Institute, Vibration Institute or BINDT, and completion of both the online learning and public classroom training components.

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.
