Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

UEPMNT440 - Diagnose and repair faults in power plant inverter systems

What evidence can you provide to prove your understanding of each of the following citeria?

Verify fault

  1. Normal performance and function of inverter system equipment is ascertained by consulting appropriate personnel and reference sources, in accordance with workplace procedures
  2. Fault indicators, technical information and diagnostic techniques are used to verify reported faults, in accordance with workplace procedures
  3. Faults are reproduced and monitored, if possible, in accordance with workplace procedures
  4. Isolations are confirmed, where appropriate, in accordance with workplace procedures
  5. Equipment components, wires and terminations are inspected for faults, in accordance with workplace procedures
  6. Diagnostic techniques are selected and used, in accordance with workplace procedures
  7. Components are disconnected to enable accurate test measurements of suspected faulty components, without concern of back feed readings, in accordance with workplace procedures
  8. Test and measurement instruments are used, in accordance with workplace procedures and manufacturers' instructions
