Description
This unit of competency covers the ability to apply National Test Procedures to determine whether a non-automatic weighing instrument (<3 tonne) or catchweigher is suitable for trade and then mark it accordingly. It also involves auditing the performance of verifiers who have previously tested and marked limited weighing instruments for use.

EVIDENCE GUIDE
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 weighing 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 weighing 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:
limited weighing instruments, test equipment and reference standards
computer and relevant software and/or organisation information management system
Certificates of Approval for instruments
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 verify 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 allocated a task of verifying a digital weighing instrument at a butcher's premises. In preparation for this visit, the inspector accesses the organisation's database to establish the type of instrument to be tested and any previous history of the instrument or trader. The equipment required for this inspection is identified, accessed and stowed in the vehicle securely and safely. Particular attention is made to ensure the integrity of the reference standards is maintained and that they are still current according to their verification certificate. On arrival at the butcher's premises, the inspector introduces him/herself to the manager and explains the purpose of the visit and the process involved. During this discussion the inspector explains that he/she will inspect the instrument for compliance with its Certificate of Approval, assess the instrument's operating environment for factors that may impact on its performance and conduct the visual and performance tests in accordance with the National Test Procedure. If it complies with these requirements, he/she will mark the instrument as being acceptable for trade use and complete all the required inspection documentation.
During the inspection the inspector finds that the instrument has a tare capacity greater than that stated in the Certificate of Approval and the weighing performance of the instrument exceeds the maximum permissible error stated in the national measurement regulations. As a result, the inspector removes the previous verification mark from the instrument and issues the butcher a warning that the instrument cannot be used for trade until it has been corrected and verified again. Before leaving the premises, the inspector examines a sample of prepacked articles and the trading practices used by the trader for compliance with trade measurement legislation.
