Evidence of competence in this unit must satisfy all of the requirements of the elements and performance criteria, and include demonstration of:
completing initial verification testing for at least three (3) classes of instruments.
accessing and correctly interpreting documentation required for inspections, evaluation of measuring instruments and verifier audits
ensuring test equipment, reference standards or reference materials are fit for purpose in accordance with applicable legislation and organisational procedures
planning, preparing for, and safely conducting inspections to maximise outcomes and minimise disruption to the public and trader
checking compliance and evaluating the performance of instruments using appropriate Certificate of Approval, National Measurement Institute (NMI) policy and National Instrument Test Procedures, and adjusting for any impact of the operating environment
reliably determining if instruments are suitable for trade use in accordance with legislative requirements
conducting at least two (2) verifier instrument audits to assess the performance of verifiers who test and mark simple measuring instruments for trade use
assessing verifier performance against expected outcomes and analysing any variances to identify isolated or systemic problems
identifying potential non-compliance of trading practices (applicable to the instrument) with national measurement legislation and initiating an efficient inspection strategy that has a limited impact on others
acting on non-compliance of instrument or verifier performance and/or trading practices with national measurement legislation and initiating appropriate enforcement action
demonstrating professionalism and respecting the rights of the trader at all times
using routine communication and negotiation skills to:
explain the purpose of inspection
inform traders of non-compliances and consequences of failing to rectify them
explain procedures and inspection outcomes to traders, verifiers and managers
using numeric skills to:
perform specified calculations involving fractions, decimals, ratios, proportions and percentages
use correct units and the correct number of significant figures
analyse performance results over a single or limited range of operating conditions
maintaining the security and confidentiality of data in accordance with organisational and regulatory requirements
reporting results in the required formats and expected timeframe
working safely.
