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!

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

applying relevant WHS practices

using approved repair/overhaul procedures and processes relating to instrument system components

recognising the serviceability state and repair or overhaul requirements for:

mechanical instruments

electro-mechanical instruments

instrument sensors

applying logic processes, and using test equipment and appropriate wiring diagrams and manuals to isolate components faults

performing component testing to isolate/confirm component fault and assess post-repair/overhaul serviceability

correctly disassembling, inspecting component parts, repairing/ replacing/modifying component parts and assembling components listed above

correctly interpreting instrument and display information, symbols and readings.

It is essential that system component testing procedures, cleanliness requirements and safety precautions applicable to the instrument system components being maintained are fully observed, understood and complied with. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice across a range of inspection, testing and troubleshooting applications (including the timely involvement of supervisors or other trades) is critical.

Evidence of transferability of skills and knowledge related to repair is essential. This may be demonstrated through application across a representative range from within the components listed in the Assessment Conditions.

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

component and system operation

the basic function and operation of the following components to enable testing for fault isolation/confirmation, to determine repair or overhaul requirements, and serviceability status post-repair or overhaul:

mechanical instruments

electro-mechanical instruments

instrument sensors

basic principles/functions relating to the above components and associated with:

alternating current (AC) and direct current (DC) synchronous systems

servomechanisms

gyroscopes

vacuum and pressure-based indication methods (pitot/static and pressurisation)

advanced analogue fundamentals

electro-mechanical sensor signal generation.
