Application

This unit of competency defines the skills and knowledge required to determine system specification and control loop characteristics, and test, monitor and record system operation.

It applies to localising the fault condition; repairing or replacing faulty condition; calibrating, configuring and adjusting complex control systems; and recommissioning the system.

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.

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