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 check equipment for correct operation and validate/calibrate precision measuring 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 calibrating measuring 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, supervisor's 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.

Guidance information for assessment

Required skills

Look for evidence that confirms skills in:

interpreting work requirements

using appropriate tools and equipment to check measuring equipment for faults

using appropriate techniques to check the calibration of the measuring equipment for conformance to specifications

calibrating the measuring equipment against the appropriate physical standard

recommissioning the measuring equipment

using literacy and numeracy skills to enable correct completion of calibration records

Required knowledge

Look for evidence that confirms knowledge of:

measuring equipment specifications, operation, wearing parts, connections and components

checks that are to be made of the measuring equipment and the tools and equipment to be used when checking the measuring equipment

common fault(s) that may be found in the measuring equipment

effects of faults on the performance/accuracy of the measuring equipment

general knowledge of standards, legislative or regulatory requirements applicable to the measuring equipment and/or its calibration

standard operating procedures for calibrating the measuring equipment and the tools and equipment required to do so

standard operating procedures for commissioning the measuring equipment

calibration records to be kept/maintained in accordance with standard operating procedures

hazards and controls associated with calibrating measuring equipment

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Calibration

To standardise the quantities of a measuring instrument

Physical standards

Reference standards of mass length, time, temperature, pressure, volume, process characteristics etc.

Calibration devices, equipment

Micrometer, vernier caliper, voltmeter, oscilloscope, all types of comparators, jigs and fixtures, templates and patterns etc.

Techniques

In standard operating procedures, manufacturers' manuals

Recommissioned

Sealing, tagging, identification or storage in accordance with standard operating procedures
