Vibration Analysis Category II
PCN certificated Vibration Analysis Category II personnel are qualified to perform industrial machinery vibration measurements and basic vibration analysis
using single channel measurements, with or without phase trigger signals, according to established and recognised procedures. They require all the knowledge, experience and skills expected of Category I, and in
addition they shall at least:
□ be able to define the measurement activities
to be undertaken by a category I individual in the course of routine data collection;
□ be aware of and capable of using the basic principles of signal analysis and, as such, can define acquisition and analysis settings to collect data appropriate to the
machine(s) monitored;
□ be able to perform basic (single channel) impact tests to determine natural frequencies;
□ be able to interpret and evaluate test results and acceptance tests in
accordance with specifications and standards;
□ be able to diagnose common
fault indications and recommend basic corrective actions commensurate with their area of machinery experience including carrying out single-plane balancing of rigid rotors with or without phase;
□ be able to provide technical guidance to and instruct Category I personnel.
