Application
This unit of competency defines the skills and knowledge required to test and diagnose faults in electronic quartz watches.
It applies to diagnosing faults where the power cell performance has already been tested and its condition is assessed as good or the correct terminal voltage under load, but the watch continues to indicate faults or is stopped.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
