Elements and Performance Criteria

1. Test instrumentation systems and equipment
   • Work/test requirements are identified and defined to standard operating procedures.
   • Correct test application principles are selected after inspection of instrumentation systems, equipment/components.
   • Appropriate test equipment is selected in accordance with defined requirements.
   • Device isolation methods/requirements are observed and localised.
   • Appropriate test procedures and application principles are applied in assessing operation of instrumentation systems, equipment/components.
   • Normal operating characteristics of instrumentation systems, equipment/components are applied to the level necessary to identify and localise faults.
   • Characteristics/operational function assessment procedures are applied according to safety and regulatory/site specifications.
   • Characteristics and operational function is checked and verified.
2. Apply data collection techniques and localise fault conditions
   • Drawings/diagrams and operational specifications are utilised in identifying and localising fault conditions.
   • Where appropriate, built-in fault indicators, error codes are examined and correctly interpreted and results are recorded to standard operating procedures.
   • Fault condition is localised to major component level using appropriate test equipment principles and procedures.
3. Analyse and report test results
   • Test results are analysed/verified against operational specifications and localised faults are confirmed.
   • Potential and real faults are reported using standard operating procedures.
   • Faulty conditions are evaluated and corrective action is planned.
   • Action plan is recorded and documented according to standard operating procedures.
4. Calibrate instrumentation equipment/components
   • Zero, span and range checks are undertaken on indicators/controllers using correct and appropriate configuration.
   • Where applicable, methods of adjustment using calibration devices are performed and documented to prescribed procedures and operational specifications.

Evidence Required

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
Overview of assessment	A person who demonstrates competency in this unit must be able to fault find test calibrate instrumentation systems and equipment Competency in this unit cannot be claimed until all prerequisites have been satisfied
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria including required knowledge and be capable of applying the competency in new and different situations and contexts
Context of and specific resources for assessment	This unit may be assessed on the job off the job or a combination of both on and off the job Where assessment occurs off the job that is the candidate is not in productive work then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team The assessment environment should not disadvantage the candidate This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with fault finding testing calibrating instrumentation systems and equipment or other units requiring the exercise of the skills and knowledge covered by this unit
Method of assessment	Assessors should gather a range of evidence that is valid sufficient current and authentic Evidence can be gathered through a variety of ways including direct observation supervisors reports project work samples and questioning Questioning techniques should not require language literacy and numeracy skills beyond those required in this unit of competency The candidate must have access to all tools equipment materials and documentation required The candidate must be permitted to refer to any relevant workplace procedures product and manufacturing specifications codes standards manuals and reference materials
