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 the appropriate test equipment and measure the values of electrical quantities of the circuits
- Use calculations to verify the measured values of the electrical quantities in a series and in a parallel circuit configuration
- Compare the measured values to the calculated values, and determine the reasons for any variations
- Measure LV, ELV and TNV voltages to determine that the value is 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 working 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 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
- 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 the output voltage of a digital device for ‘high’ and ‘low’ logic states
- Perform cable selection
