Description
This unit covers analysing a simple circuit by identifying the function and operation of the circuit and circuit components contained within approved manufactured products.
Notes
Elements and Performance Criteria
1. Establish function and purpose of selected circuit
  • 1.1. All relevant drawings, specifications, manuals and documentation are obtained and interpreted in accordance with workplace procedures.
  • 1.2. Circuit and component installation is observed where required to establish function and purpose.
  • 1.3. Safety procedures to be followed are determined in conjunction with supervisors and in accordance with legislative and regulatory requirements.
  • 1.4. Appropriate personnel are consulted with to establish job requirements.
2. Extract a circuit diagram from existing drawings and documentation
  • 2.1. Appropriate components and assemblies are identified.
  • 2.2. Where required, components and/or materials are identified from supplier/manufacturer catalogues.
  • 2.3. Circuit diagram is extracted.
  • 2.4. Drawing conventions and symbols are used in the diagram in accordance with codes and workplace procedures.
3. Analyse the circuit for electrical characteristics
  • 3.1. Functions of the circuit and components are compared against design characteristics and operational specifications.
RANGE STATEMENT
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.
Components and assemblies
Can include:
resistors - fixed (composition and wire wound), variable (rheostats, potentiometers and trimmers), non-linear (thermistors)
capacitors - fixed (ceramic, plastic and electrolytic), variable, magnetic, transformers (AF, RF and power), chokes, relays, contactors, rectifiers, smoothing filters, voltage regulators and feedback
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 analyse the functions and components of a simple electrical system circuit. 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. Where assessment occurs off the job, i.e. the candidate is not in productive work, an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered 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 analysing a simple electrical system circuit 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.
