Description
This unit of competency defines the skills and knowledge required to test, diagnose and fault find electronic control systems associated with mobile and stationary plant and equipment. It applies to whole of equipment diagnosis and rectification and complements diagnostic and rectification skills contained in individual system units of competency. Where electronic systems associated with communication between the mobile or stationary plant and external communication sources such as those used for remote guidance or monitoring unit MEM27018 Test, diagnose and rectify mobile and stationary plant external monitoring and control systems should also be selected.Where the repair of electronic circuitry associated with these systems. is required unit MEM18056 Diagnose and repair analog equipment and components and unit MEM18057 Maintain/service analog/digital electronic equipment, should also be selected as appropriate.No licensing, legislative or certification requirements apply to this unit at the time of publication.Band: AUnit Weight: 4
