Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit's learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines. Students will be expected to demonstrate the following required skills: - using diagnostic skills to identify and correct faulty operation; - managing multiple processes; - interpreting and using relevant circuit diagrams, specifications, schematics; - locating reading/recording built-in fault indicators; - interpreting error code documents; - isolating electrical circuits from the power supply; - tagging isolated circuits; - verifying circuit isolation; - confirming/localising circuit faults using appropriate test equipment, work techniques and tools; - recording/reporting faults in electrical circuits; - repairing/adjusting electric circuits; - confirming circuit/s against specification, and; - recording rectification of the circuit(s).Students will also be expected to demonstrate the following knowledge: - circuit characteristics; - hazards associated with the electrical circuit(s); - relevant regulatory requirements; - errors indicated by built-in devices; - circuit isolation procedures; - common electrical test instruments and their application; - common techniques for testing electrical circuits; - recording/reporting requirements for electrical circuit faults; - appropriate techniques/procedures for returning the circuit/s to specification; - site/manufacturers' circuit specifications; - requirements for recording circuit rectifications; - any applicable industry standards, national/Australian standards, NOHSC guides, State/Territory regulatory codes of practice/standards; - use and application of personal protective equipment, and; - safe work practices and procedures.
