Unit Descriptor
Unit descriptor |
This unit covers locating faults in analogue electronic equipment or sub-assemblies, and replacing faulty components. |
Application of the Unit
Application of the unit |
This unit applies to electronic systems or equipment including amplifiers, analogue hardware, communication, consumer audio/video, electronic appliances, scanning systems, security/fire systems, power supplies and test equipment etc. All specifications and procedures are gained from schematics, circuit drawings, engineering data sheets or manufacturers' handbooks. Unit MEM05002B (Perform high reliability soldering and desoldering) must also be selected if soldering of components is required to advanced or military specifications, where the reliability of electrical connections is critical, or where surface mounted devices are being soldered/de-soldered. 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. Band: This unit has dual status and is to be regarded as both a Specialisation band A unit and Specialisation band B unit for progression to C7 (AQF level IV). Unit Weight : 10 |

Elements and Performance Criteria Pre-Content
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
1. Locate fault in electronic system/sub-assembly |
1.1. System/sub-assembly functions and principles are determined with reference to equipment manuals, circuit diagrams etc. 1.2. Built-in test functions are run and fault indicator error codes and appropriate maintenance records are checked and reviewed. 1.3. Fault symptoms are reproduced, where appropriate, and verified using appropriate fault finding techniques. 1.4. Where appropriate, faulty sub-assembly is isolated and removed from electronic system using correct and appropriate tools and techniques. 1.5. Sub-assembly is checked and tested using correct and appropriate test equipment and fault finding techniques. 1.6. Faulty component/s are identified and/or fault cause is isolated. |
2. Repair/replace faulty components |
2.1. Faulty component is removed, where required, using correct and appropriate tools and techniques. 2.2. Faulty component is repaired/replaced in accordance with manufacturers' recommended procedures or to standard operating procedures. 2.3. Repaired/replacement components are fitted in accordance with manufacturers' recommended procedure or to standard operating procedures using correct and appropriate tools and techniques. 2.4. Where appropriate, repaired sub-assembly is refitted to electronic system using correct and appropriate tools and techniques. 2.5. Systems/sub-assembly is checked and tested for correct operational compliance with specifications utilising correct and appropriate test procedures and equipment. |

Evidence Guide
EVIDENCE GUIDE |
|
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 diagnose and repair analog equipment and components. 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 diagnosing and repairing analog equipment and components, 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 |
Range Statement
RANGE STATEMENT |
