What an assessment for UEEEC0024 must cover

37 assessable components: 3 elements (19 performance criteria), 10 performance evidence and 8 knowledge evidence requirements. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Prepare to diagnose and rectify electronic display circuit faults

  • 1.1Work health and safety (WHS)/occupational health and safety (OHS) requirements and workplace procedures for a given work area are identified and applied
  • 1.2WHS/OHS risk control measures and workplace procedures are followed in preparation for the work
  • 1.3Safety hazards which have not previously been identified are risk assessed, documented and risk control measures devised and implemented in consultation with appropriate person/s
  • 1.4Extent of faults is determined from reports, documentation and discussions with appropriate person/s
  • 1.5Appropriate person/s is consulted to ensure the work is coordinated effectively with others involved on the worksite
  • 1.6Tools, equipment and testing devices needed to diagnose faults are obtained in accordance with workplace procedures and checked for correct operation and safety

2 Diagnose and rectify electronic display circuit faults

  • 2.1WHS/OHS risk control measures and workplace procedures for carrying out electronic display circuit work are followed
  • 2.2Need to test and measure live work is determined in accordance with WHS/OHS requirements and, as required, conducted in accordance with workplace safety procedures
  • 2.3Circuits/machines/plant are checked and isolated in accordance with WHS/OHS requirements and workplace procedures
  • 2.4Logical diagnostic methods are applied to diagnose display circuits faults, employing measurements of circuit operating parameters referenced to display operating specifications
  • 2.5Suspected fault scenarios are tested as being the source of display circuit problems
  • 2.6Faults in the electronic components of the display circuits are rectified to display circuits operation and industry standards
  • 2.7Circuits are tested to verify that the display operates as intended in accordance with industry standards and to specified requirements
  • 2.8Unplanned situations are responded to in accordance with workplace procedures, discussions with appropriate person/s and consistent with job specifications and requirements in a manner that minimises risk to personnel and equipment
  • 2.9Diagnosis and rectification activities are carried out efficiently without waste of materials or damage to apparatus, the surrounding environment or services using sustainable energy practices

3 Complete and report fault diagnosis and rectification activities

  • 3.1WHS/OHS work completion risk control measures and workplace procedures are followed
  • 3.2Worksite is made safe in accordance with workplace safety procedures
  • 3.3Rectification of faults is documented in accordance with workplace procedures
  • 3.4Appropriate person/s is notified in accordance with workplace procedures that display circuit faults have been rectified

Performance evidence

  • applying logical diagnostic methods
  • using fault scenarios to test the source of circuit faults
  • identifying the cause faults using logical diagnostic methods
  • rectifying faults effectively
  • verifying that the display operates correctly
  • documenting fault rectification
  • dealing with unplanned events
  • applying relevant work health and safety (WHS)/occupational health and safety (OHS) requirements, workplace procedures and practices, including using risk control measures
  • applying sustainable energy principles and practices
  • connecting test/measuring devices into a circuit in accordance with industry standards

Knowledge evidence

  • electronic displays faults, applying safe working practices and relevant standards, codes and regulations, including:
  • cathode ray tube displays encompassing: operation and characteristics of various types of cathode-ray tubes, including delta, in-line and precision in-line; voltages, statics and x-rays around cathode ray tubes; set-up and adjustment techniques; rear and front projection television systems; typical faults
  • plasma displays and their circuit control operation encompassing: advantages of flat panel displays (over conventional cathode ray tubes and raster geometry); theory of plasma gas discharge and phosphor excitation; scanning techniques (column/row addressing); luminance/colour aspects (the need to re-address pixels to control light output); gamma correction considerations (reversal of the gamma correction that is carried out at the television studio to compensate for the non-linearity of light output of a conventional cathode ray tube; plasma flat panel construction (and handling)
  • liquid crystal displays and the control circuit operation encompassing: principles of transmissive liquid-crystal display (LCD) (as opposed to reflective types); light polarisation (polarisation twisting characteristics of liquid crystal and the need for polarisation filters in display panel); voltage/current requirements and need for electric field; fluorescent back light (need for high frequency operation and power requirements); scanning techniques (colour/row addressing and thin film transistors); light attenuation (caused by the many layers/filters the back light has to pass through); construction and handling
  • display circuit diagnostics encompassing: sub-system components (i.e. functional blocks) and their operating parameters; factors effecting system performance; typical faults, their symptoms and cause; fault diagnosis procedures and testing; sub-system adjustments
  • advance electronic measuring instruments encompassing: test/measuring devices and their application: frequency counters and synthesisers, spectrum analysers, noise and distortion meters, and radio frequency (RF) communications service monitor
  • connection of test/measuring devices into a circuit encompassing: safety procedures; loading and matching; storage and delay; circuit arrangement of test/measuring devices; taking and interpreting readings; notion of decibels, including dBm, dBr, dBu and dBo
  • WHS/OHS enterprise responsibilities encompassing: provisions of relevant WHS/OHS legislation; principles and practice of effective WHS/OHS management; management arrangements relating to regulatory compliance; enterprise hazards and risks, control measures and relevant expertise required; characteristics and composition of workforce and their impact on WHS/OHS management; relevance of enterprise management systems to WHS/OHS management; analysis of working environment and design of appropriate WHS/OHS management systems; analysis of relevant data and evaluation of WHS/OHS system effectiveness; assess resources to establish and maintain WHS/OHS management systems; relevant manufacturer specifications; relevant workplace documentation; relevant workplace policies and procedures

Questions about assessing UEEEC0024

What does an assessment tool for UEEEC0024 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for UEEEC0024 needs to address all 37 unit components: 3 elements with 19 performance criteria, 10 performance evidence requirements, 8 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for UEEEC0024?

Auditori pulls the current release of UEEEC0024 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for UEEEC0024 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing UEEEC0024 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of UEEEC0024, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
