Course 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.

Application of the unit:
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 Territory.
Work is carried out under supervision

Pre-requisite Courses and Assumed Knowledge and Capabilities

Overview of Assessment

Assessment may incorporate a variety of methods including written/oral activities and demonstration of practical skills to the relevant industry standards. Participants are advised that they are likely to be asked to personally demonstrate their assessment activities to their teacher/assessor. Feedback will be provided throughout the course. Evidence of student’s competence can be gathered through a variety of ways including:
• observation of processes and procedures;
• oral and/or written questioning on required knowledge and skills;
• testimony from supervisors, colleagues, clients and/or other appropriate persons;
• inspection of the final product or outcome;
• a portfolio of documentary evidence.

Graded Assessment out of 100 Marks will be based on the results obtained for Assignments, Practical & Final Exam 
Students must gain a pass in ALL forms of assessment in order to gain this competency.
