2. Phase-angle voltmeters
3. Oscilloscopes (dual differential, differential, delayed time base, storage)
4. Current probes
5. Logic and discrete component testers
6. Electronic component substitution boxes and miscellaneous test adapters

Overview of assessment
A person who demonstrates competency in this unit must be able to use electronic test equipment to measure electronic circuit parameters while observing all relevant safety precautions

Critical aspects for assessment and evidence required to demonstrate competency in this unit
The underlying skills inherent in this unit should be transferable into all areas that require the use of electronic test equipment as listed in the Range Statement. It is essential that the general aspects of electronic test equipment selection, preparation for use and safe application to a representative range of measurement and testing tasks are clearly understood.
Evidence of knowledge about the selection and use of the range of test equipment listed in the Range Statement, and of the methods used to identify applicable polarity and connection to components and circuits for required measurement or testing.
A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements of the Unit of Competency are being achieved under routine supervision, with each item of test equipment in Groups 1 to 6 in the Range Statement having been used to measure electronic circuit parameters and test performance. This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide.

Context of and specific resources for assessment
Competency should be assessed in the work environment, or simulated work environment, using electronic test equipment specified in maintenance documentation. It is also expected that applicable test equipment can be selected on the basis of general trade knowledge where specific test equipment is not specified.
