MCCCD Official Course Competencies
1. Explain the basic differences between emergency systems, legally required standby systems, and optional standby systems. (I)
2. Draw a basic instrument channel diagram including a measuring element, transducer, and transmitter. (II)
3. Discuss the three-point and five-point methods of calibration. (III)
4. Demonstrate common maintenance practices for control valves and actuators. (IV)
MCCCD Official Course Competencies must be coordinated with the content outline so that each major point in the outline serves one or more competencies. MCCCD faculty retains authority in determining the pedagogical approach, methodology, content sequencing, and assessment metrics for student work. Please see individual course syllabi for additional information, including specific course requirements.
