Application
This unit of competency defines the skills and knowledge required to locate, replace/repair faulty components in microprocessor-based equipment.
It applies to situations in which the individual has sufficient information and access to microprocessor components to diagnose the functioning of elements within the microprocessor and requires an understanding of machine and assembly language and address and bus systems.
Where diagnosis of analog components is required unit MEM18056 Diagnose and repair analog equipment and components should also be selected.
Where routine fault finding within microprocessor systems is required unit MEM18057 Maintain/service analog/digital electronic equipment should also be selected.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Band: B
Unit Weight: 6
