Qualification -
Unit of Competency MSATMINS501A - Inspect a range of complex measuring instruments
Description This unit of competency covers the ability to apply National Test Procedures to determine whether a complex measuring instrument is suitable for trade use. It involves the ability to perform lengthy calculations to assess instrument performance and conduct tests that may require coordination of a range of resources over long durations in hazardous environments. This unit also involves auditing the performance of verifiers who have previously tested and marked instruments for use.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit of competency is applicable to trade measurement inspectors appointed under national measurement legislation who may inspect a range of complex measuring instruments as part of their allocated duties. Complex measuring instruments are used in a wide range of heavy industries. For example, automatic rail weighbridges, belt weighers, totalising hoppers and liquid petroleum gas (LPG) flow meters are used throughout the mining, road/rail freight and petroleum/gas industry sectors.Industry representatives have provided case studies to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting. These are found at the end of this unit of competency under the section 'This competency in practice'.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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

Competency must be demonstrated in the ability to perform consistently at the required standard for any class of complex instrument listed in the Range Statement.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors should ensure that candidates can:

identify, access and apply test procedures

identify and use suitable reference standards

evaluate and adjust the impact of the operating environment on the performance of the instrument

analyse test results to determine the instrument's suitability for verification (trade use)

identify the scope of a verifier performance audit and assess results with expected outcomes

audit the performance of verifiers of complex measuring instruments

identify and implement additional inspection strategies for non-instrument related breaches of national measurement legislation

recognise and act on non-compliance

maintain the security and confidentiality of data in accordance with organisational and regulatory requirements

report results in the required formats and expected timeframe.

Context of and specific resources for assessment

This unit of competency is to be assessed in the workplace or simulated workplace environment.

This unit of competency may be assessed with:

MSATMREF301A Use and maintain reference standards.

Resources may include:

access to a complex instrument, test equipment and reference standards

computer and relevant software and/or organisation information management system

Certificates of Approval for the instrument

relevant legislative and organisational procedures.

Method of assessment

The following assessment methods are suggested:

questions to assess understanding of relevant procedures, licensing requirements, trader obligations and remedial actions

review of inspection reports and verifier performance audit reports prepared by the candidate

feedback from supervisors and peers regarding the candidate's ability to inspect the performance of instruments in accordance with legislative and organisational procedures

observation of the candidate conducting an inspection.

In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly. Questioning techniques should suit the language and literacy levels of the candidate.

This competency in practice

Industry representatives have provided the case studies below to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting.

An inspector has been given the task of inspecting a bulk flowmetering system at an oil company distribution terminal. In preparation, the inspector evaluates the instrument nominated for inspection, identifies and accesses appropriate documentation for the inspection, identifies and accesses equipment, evaluates previous inspection data and develops an inspection strategy.The inspector visits the terminal to discuss the proposed inspection strategy with the site controller. During this discussion, the inspector discovers that access to the instrument has been restricted and modifications will have to be made to the area surrounding the instrument. The site controller engages a contractor to make the necessary modifications and agrees on an inspection strategy that will minimise disruption to terminal operations.

On completion of the modifications, the inspector returns to the terminal to inspect the bulk flowmetering system. The site controller has arranged for all the resources identified at the inspection strategy meeting to be available. Prior to commencing any testing, the inspector holds a meeting with all personnel involved in the inspection and describes the inspection strategy. A fitter who will be operating the instrument identifies a problem and offers a solution. The inspector agrees and adjusts the inspection strategy accordingly.At the completion of the testing, the inspector uses the recorded data in combination with a variety of data derived from correction tables and complex mathematical formulae to determine performance result for the instrument.These results confirm the instrument's performance is outside the acceptable maximum permissible errors. The inspector informs the site controller of the outcome and issues a formal warning explaining that the instrument cannot be used for trade until it has been corrected and verified by a licensed verifier.During a follow up visit, the inspector confirms the instrument has been repaired and verifies it.
