Elements and Performance Criteria
- Connect up, test and verify DC and AC circuitry
- Identify any hazards and work health and safety (WHS) issues for a safe work site, and notify appropriate personnel
- Connect a series and a parallel DC and AC circuit configuration following safe work practices
- Choose appropriate test equipment and measure values of electrical quantities of circuits
- Use calculations to verify measured values of electrical quantities in a series and in a parallel circuit configuration
- Compare measured values to calculated values, and determine reasons for any variations
- Measure low voltage (LV), extra low voltage (ELV) or telecommunications network voltage (TNV) to determine if values are within equipment or power supply specifications
- 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
- Test residual current devices (RCD) or earth leakage devices to ensure they are operational prior to working with AC mains powered equipment, power supplies and tools
- Evaluate results and determine probable faults, if relevant
- Evaluate analog and digital signals
- Compare characteristics of an analog signal and a digital signal
- Produce a layout using building blocks to represent a typical analog and a digital circuit showing different characteristics between an analog signal and a digital signal
- Produce 4-bit binary codes with their decimal equivalent to represent output voltages of a digital to analog converter
- Choose appropriate test equipment and measure output voltage of a digital device for high and low logic states
- Perform cable selection
