This unit applies to the testing and maintenance of electronic equipment and systems, where a series of checks and pre-determined tests is applied in accordance with workshop manuals, testing procedures etc. Checks, tests and calibrations apply to a wide range of electronic systems and sub-assemblies used in engineering environment including telecommunication, process control, computer systems, security monitoring and alarm systems, etc.

This unit also covers the replacement of faulty components identified during these tests.

Where termination of cables is involved, Unit MEM10002B (Terminate and connect electrical wiring) and/or Unit MEM18063B (Terminate signal and data cables) must also be selected.

If diagnosis and repair of electronic equipment is undertaken to component level, UnitMEM18056B (Diagnose and repair analog equipment and components) and/or Unit MEM18065B (Diagnose and repair digital equipment and components) should also be selected.

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 maintain/service analog/digital electronic 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 maintaining/servicing analog/digital electronic 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.

Guidance information for assessment

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Electronic equipment

Amplifiers, analogue/digital hardware, communication, consumer audio/video, electronic appliances, scanning systems, security/fire systems, power supplies and test equipment etc.

Components

Discrete component, circuit boards, connectors, plug-in items, power supplies and the like

Test equipment

Includes the use of voltmeters, ammeters, cathode ray oscilloscopes, frequency counters, continuity testers etc.
