Performance Criteria |
|
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
|
1. Connect up, test and verify DC and AC circuitry |
1.1 Identify any hazards and work health and safety (WHS) issues for a safe work site, and notify appropriate personnel 1.2 Connect a series and a parallel DC and AC circuit configuration following safe work practices 1.3 Choose the appropriate test equipment and measure the values of electrical quantities of the circuits 1.4 Use calculations to verify the measured values of the electrical quantities in a series and in a parallel circuit configuration 1.5 Compare the measured values to the calculated values, and determine the reasons for any variations 1.6 Measure LV, ELV and TNV voltages to determine that the value is within equipment or power supply specifications 1.7 Use appropriate test equipment to measure AC voltage (multimeter) or AC current (clamp meter) in a safe manner that does not require an LV circuit to be disconnected 1.8 Test residual current devices (RCD) or earth leakage devices to ensure they are working prior to working with AC mains powered equipment, power supplies and tools 1.9 Evaluate results and determine probable faults if relevant |
|
2. Evaluate analog and digital signals |
2.1 Compare characteristics of an analog signal and a digital signal 2.2 Produce a layout using the building blocks to represent a typical analog and a digital circuit showing the different characteristics between that of an analog signal and a digital signal 2.3 Produce 4-bit binary codes with their decimal equivalent to represent output voltages of a digital to analog converter 2.4 Choose appropriate test equipment and measure the output voltage of a digital device for ‘high’ and ‘low’ logic states |
|
3. Perform cable selection |
3.1 Compare basic transmission characteristics of different types of cables used in telecommunications and select the most appropriate cable type to suit application characteristics 3.2 Connect two devices with a patch cable and test the connection |

Evidence Guide
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

|
|
Methods of assessment |
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:
|
|
Guidance information for assessment |
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
Aboriginal people and other people from a non-English speaking background may have second language issues. Access must be provided to appropriate learning and assessment support when required. Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed. In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. Where applicable, physical resources should include equipment modified for people with special needs. |
