Unit of Competency | MEM30025A - Analyse a simple electrical system circuit |
---|---|---|---|
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. | ||
Employability Skills | This unit contains employability skills. | ||
Learning Outcomes and Application | This unit applies to all manufacturing environments. It covers analysis of existing circuits against specifications only and does not extend to determining modifications to circuits. This unit does not cover the skills involved in direct measuring of values requiring connecting or disconnecting of circuits and components covered by licensing requirements. Where such values are required they are to be obtained through the assistance of appropriately licensed personnel or through undertaking the specified training for the appropriate licence. Work is conducted in accordance with regulatory and legislative requirements in each State and TerritoryWork is carried out under supervision.Band: 0Unit Weight: 0 | ||

Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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. |

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Required skills |
Look for evidence that confirms skills in: calculating reading and interpreting specifications and drawings drawing to scale analysing planning and sequencing operations checking and clarifying task-related information checking for conformance to specifications |
Required knowledge |
Look for evidence that confirms knowledge of: safe work practices and procedures hazard and control measures associated with analysing the function of a simple electrical system circuit dangers and safety precautions: electrical hazards earthing and insulation The function of the following components: 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 basic physics: conductors insulators semiconductors current flow voltage resistance colour code power rating Ohm's Law electrical units power in electrical circuits protection methods: fuses circuit breaking safety interlocks earthing - personnel safety a.c. circuits: series and parallel a.c. circuits power in a.c. circuits power supplies: transformers rectifiers smoothing filters voltage regulators and feedback function and operation of a simple low voltage d.c. power supply function and operation of the transformer in a simple low voltage d.c. power supply, including the significance of the turns ratio function in a simple low voltage d.c. power supply of rectifiers including the significance of the diode characteristics, for both half and full wave types operation of smoothing filters in a simple low voltage d.c. power supply operation of simple zener diode type voltage regulators in a simple low voltage d.c. power supply feedback |
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 |
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
