Maintain instrumentation system components
Assessment tool
Version 1.0
Issue Date: May 2024
This unit applies to maintaining instrument system components for applications such as fixed and mobile plant and equipment, marine installations or machine and process operations.
Application of this unit would involve identifying instrumentation system components as well as inspecting and assessing component condition/operation using instrumentation principles and methods.
It would also involve the interpretation of information from data sheets and circuit diagrams in order to make repairs and replacements to predetermined site or manufacturer specifications.
For straightforward removals/replacement of components from an instrumentation system, see Unit MEM18055B (Dismantle, replace and assemble engineering components).
If higher level hydraulic and pneumatic systems knowledge is needed then Units MEM18018C (Maintain pneumatic system components ) and MEM18020B (Maintain hydraulic system components ) should also be selected.
Band: A
Unit Weight: 6
This unit covers maintaining instrument system components of a primarily mechanical nature. An understanding of instrumentation principles is required.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

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 | A person who demonstrates competency in this unit must be able to maintain instrumentation system components. 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 maintaining instrumentation system components, 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. 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. |

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Required skills |
Look for evidence that confirms skills in: obtaining relevant data with respect to the operation of the instrumentation systems/equipment locating, inspecting and testing a range of instrumentation system components isolating instrumentation system/equipment obtaining and interpreting all relevant instrumentation circuits, drawings, instructions, manuals and data sheets checking the individual components within the instrumentation system for correct operation dismantling/repairing/reassembling faulty components selecting correct replacement parts from the manufacturer/supplier catalogues checking repaired/replaced instrumentation system components for correct operation completing service reports obtaining error code interpretation documents recording/documenting test results undertaking zero, span and range checks on instrumentation systems/equipment calibrating instrumentation system/equipment |
Required knowledge |
Look for evidence that confirms knowledge of: instrumentation principles such as controlling density, level, flow, temperature, composition of a range of materials effects of resistance, capacitance, inductance and impedance (R,L,C) upon electrical circuit interpretation requirements of schematic, wiring and block diagrams and circuits basic principles of hydraulic/pneumatic/electrical flow purpose and operational function of each system component procedures and equipment for inspecting and testing instrumentation system components instrumentation system component specifications deviations from specifications procedures for repairing faulty instrumentation system components dismantling, reassembly and testing techniques correct operation of the instrumentation system procedures for recording and completing service reports safe work practices and procedures relevant hazards and control measures |
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. | |
Components | Include sensors, transmitters, converters, indicators, analysers, controllers, transducers, power supplies, removable circuit boards and sensor units associated with determining/controlling density, level, flow, temperature, composition etc. of a range of materials |
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
Observation Checklist
