12066  Operate telemetric and electronic equipment and scientific instrumentation  Level 4  NQF Level 04  12   

PURPOSE OF THE UNIT STANDARD 
The qualifying learner will be able to read and interpret data from a range of electronic equipment to measure, relay and record information relating to quality and quantity of water and wastewater. Learners will be able to monitor the status of the water and wastewater treatment process by looking at information on computer screens including warning messages and data logger. This unit standard will benefit learners in that it creates portability to enable the learner to use the skills obtained in the chemical manufacturing and production fields. This will ensure that the work is economically operated and maintained according to work specifications. This competence will equip the learner with skills that are portable into other sectors thus enhancing the employability of the learner in both the water sector and other industry related jobs.

    REREGISTRATION HISTORY 
    As per the SAQA Board decision/s at that time, this unit standard was Reregistered in 2012; 2015. 

    UNIT STANDARD NOTES 
    This unit standard replaces unit standard 12066, "Operate telemetric and electronic equipment and scientific instrumentation", Level 4, 12 credits.

    Integrated Assessment:

    When conducting assessments, assessors must ensure that they are familiar with the full text of the unit standards being assessed. Assessors must ensure that the assessment covers the specific outcomes, critical cross-field outcomes and essential embedded knowledge by developing assessment activities and tools, which are appropriate to the contexts in which the learners are working. These activities and tools may include self-assessment, peer assessment, formative and summative assessment. It may be more effective and efficient to assess a number of unit standards together in an integrated way, thus reducing the overall number of assessments and ensuring that commonalities that exist between a number of unit standards are captured in a way that makes sense for assessment.

    Assessment Option:

    Learners could be assessed using the following methods:
  • Oral or written questions.
  • Observation.
  • Simulation.
  • Product sample reports.
