The unit applies to undertaking test procedures to determine the correct operational function of electrical, electronic mechanical, fluid power systems, equipment, components and associated items.

It extends to the use of mechanical, pneumatic/electro-pneumatic, electronic (analog/digital) and associated instruments, measuring variables such as temperature, level, pressure, flow rate, current, resistance, voltage, levels, light, density or any other process variable.

Tasks are undertaken in workshop/site, laboratory environments.

Operational function of instrumentation equipment/components is tested and assessed against operational specifications, and interpreted from data sheets and circuit diagrams in consultation with appropriate personnel where applicable.

Soldering/desoldering of electrical/electronic components requires the selection of Unit MEM05001B (Manual soldering/desoldering - electrical/electronic components) or Unit MEM05002B (Perform high reliability soldering and desoldering) as appropriate.

High reliability covers soldering/desoldering for the installation and fabrication of electrical/electronic components to advanced or military specifications, or where the reliability of electrical connections is critical. It also covers the soldering of electronic components where prevention of damage through electrostatic discharge or other means is required.

Band:

This unit has dual status and is to be regarded as both a Specialisation and A unit and Specialisation band B unit for progression to C7 (AQF level IV).

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

A person who demonstrates competency in this unit must be able to fault find, test, calibrate instrumentation systems and equipment. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with fault finding, testing, calibrating instrumentation systems and equipment or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.
