Application

This unit of competency defines the skills and knowledge required to select and install appropriate sensors and signal transmitters, maintain and diagnose correct operation of sensors and signal transmitters, and complete fault documentation.

It applies to planning corrective action; repairing, replacing and overhauling sensors and signal transmitters; and calibrating, testing, re-installing and recommissioning instrumentation sensors and signal transmitters.

Where soldering of components is required to advanced or military specifications, where the reliability of electrical connections is critical, or where surface mounted devices are being soldered/desoldered then unit MEM05002 Perform high reliability soldering and desoldering should also be selected.

Where diagnosis and repair of electronic equipment is undertaken to component level unit MEM18056 Diagnose and repair analog equipment and components and unit MEM18065 Diagnose and repair digital equipment and components, should also be selected as appropriate.

No licensing, legislative or certification requirements apply to this unit at the time of publication.
