- Increase your knowledge on maintenance practices, condition monitoring, and the common condition monitoring technologies
- Increase your knowledge about data collection, testing techniques, sensor types, and so on
- Learn a great deal about signal processing and the settings of your vibration analyzer
- Increase your knowledge of spectrum analysis, time waveform analysis, and phase analysis
- Understand why phase analysis and time waveform analysis are both critical tools for the vibration analyst
- Learn about common failure modes and how to detect them, including unbalance, misalignment, looseness, resonance, pump/fan/compressor vane, and flow issues, cavitation, turbulence, gearbox failures, rolling element bearing failure, and more
- Learn about high-frequency bearing and gear fault detection techniques: demodulation, enveloping, SPM HD, shock pulse, PeakVue, Spike Energy, and others
- Be able to use spectra, phase readings, time waveforms, bump and impact tests, to test for looseness, resonance, and other conditions
- Learn about precision shaft alignment and soft foot correction
- Learn about single and two-plane balancing
- Learn the basics of setting alarm limits: band alarms, and mask/envelope alarms
The key is that on the VCAT-II course you will transition from being a person who is primarily capable of collecting data to a person who can diagnose faults on the critical machinery, and in some cases, prevent or correct them.
- Why become certified by Mobius Institute Board of Certification?
- You should be recognized for your achievements; not everyone is up to the challenge of understanding vibration analysis, let alone successfully collecting data and utilizing it
- Being certified by an accredited certification organization is a major step up from simply passing a test. Yes, the process is a little more complicated and stricter, but that is for very good reasons
- The educational process is extremely valuable, but being certified tells an employer (or a consulting client) that you are capable of doing an important job
Mobius Institute has certified more vibration analysts than any other organization and we have only been offering certification since 2005. Almost 40,000 vibration analysts around the world, just like you, chose Mobius Institute for a good reason.
You will receive a digitally encrypted certificate, an ID card, and a personalized logo that you should use in email signatures and elsewhere that you want people to know about your achievements.
- VCAT-II training and certification requirements
All you need is a desire to learn and to succeed in your field. In order to be certified you must:
- Complete the training (at a public course, on-site, or on-line)
- Achieve 70% or higher on the exam (60 multiple choice questions)
- Have 18 months of practical vibration analysis work experience, verified by an independent person
If you do not have the experience, you will still receive a certificate, but you will not be officially certified. When you pass the eighteen-month milestone, you will be upgraded to full certification.

Frequently Asked Questions
Some of the more common questions regarding our VCAT-II Basic Vibration Analyst course
- CAN I SKIP THE CATEGORY I COURSE AND CERTIFICATION AND JUMP DIRECTLY TO CATEGORY II?
Yes, you may, however, please keep in mind that you should already have some vibration analysis background and training before you attempt Category II. Many people have tried to go directly to Category II and felt overwhelmed on the course. You will also need to have 18 months of field experience to be issued the ISO certificate for Category II.
- WILL I RECEIVE PRE-COURSE STUDY MATERIALS?
Every registered student will receive an instructional email to finalize their course registration. They will also receive a link to their personal Learning Zone Account. The account provides a digital version of the coursebook and also a series of folders containing movies. These movies are actual course videos, recorded in a studio, and contain the same content taught in the Instructor-led course the student is registered in.
- WHAT IS A LEARNING ZONE ACCOUNT?
Every registered student will receive an instructional email to finalize their course registration. They will also receive a link to their personal Learning Zone Account. The account provides a digital version of the coursebook and also a series of folders containing movies. These movies are actual course videos, recorded in a studio, and contain the same content taught in the Instructor-led course the student is registered in. The Learning Zone Account may be used for pre-course study materials, review during the course week, reference after the course, or used to re-take the course and re-sit your certification exam. The account is activated at the time the student registers for the course and expires 6 months after the close date of the course they will be attending.
- CAN I BUY THE LEARNING ZONE ACCOUNT AND USE IT TO STUDY FOR THE CERTIFICATION EXAM?
No, but we do offer Category I-III Distance Learning (DL) courses which are the online equivalent to our Public courses. The cost is the same as attending a Public course, the training material content is fully ISO 18436 compliant and you will be qualified to take the Certification Exam once you have completed the DL course.
You will find the distance learning courses on our shopping cart.
- DO YOU OFFER ON-SITE INSTRUCTOR LED COURSES?
Yes, we offer a range of courses that can be conducted onsite, including our Category I-IV vibration analysis courses, Asset Reliability Practitioner® ARP, ultrasound, balancing, alignment, and others. If you are in North America, please email the course category and number of students to firstname.lastname@example.org for a quotation. Outside North America, contact your local training partner.
- MAY I TAKE ONE OF YOUR COURSES IF I AM NOT INTERESTED IN BECOMING CERTIFIED OR IF I HAVE INSUFFICIENT EXPERIENCE FOR CERTIFICATION?
Yes, our courses are open to the public, regardless of experience. If you are involved in vibration analysis or rotating machinery in any capacity, such as sales, marketing, engineering, design, or reliability, you will come away with a far better understanding of how machines are monitored, how faults develop, and what can be done to determine what faults actually exist in a machine. All attendees receive certificates of completion. Candidates without sufficient experience will still receive a certificate if they pass the exam, but it will note that their experience was insufficient for ISO certification at the time.
- AFTER I ATTEND YOUR COURSE AND TAKE THE EXAM, WHEN WILL I RECEIVE NOTIFICATIONS AS TO WHETHER I PASSED, AND WHEN WILL I RECEIVE MY CERTIFICATE?
You will receive notification of your results 5-10 days after the exam has been received at our Australian office. If you have passed the exam and met all certification requirements, you will receive your Digital Certificate 10-15 days after your exam results notification email.
- HOW LONG IS THE CERTIFICATION VALID?
Vibration analysis certification is valid for five (5) years.
- HOW DO I RENEW MY CERTIFICATION?
We will endeavor to contact you before your certification expires, therefore it is important that you keep your TMS records up to date (TMS is the training management system you will use to register for the course and for certification). If you change roles, it is essential that you update your records. We also invite you to set a reminder in your calendar for five years hence to contact us.
- HOW DO I QUALIFY FOR RENEWAL?
As per the standard, we do not require you to attend our conferences or take our courses, however, we hope you will take advantage of www.mobiusconnect.com and the sites linked to Mobius CONNECT® so that your knowledge remains current. These sites are free of charge. When it is time to renew your certification, we will ask you to nominate an independent person who can verify that you are still active as a vibration analyst. There will be a small fee to renew your digital certificate and to renew your certification status with the accreditation body.
- WHAT ARE THE EXPERIENCE REQUIREMENTS FOR VCAT II?
You must have 18 months of experience in vibration data collection and analysis collection. You will be asked to nominate an independent person who can verify that you have that experience.
