This class maintains and repairs a variety of complex electronic, electro-pneumatic and electro-mechanical instrumentation.
Nature and Scope
The class is distinguished from the next lower level because of the complexity and variety of the serviced equipment. Work is performed with general supervision from an administrative superior. Assignments require evaluative thinking and are carried out in accordance with standard electronic or electro-mechanical repair and maintenance practices and general work instructions. Work is performed in the lab or on site, possibly in inclement weather.
Essential functions are fundamental, core functions common to all positions in the class series and are not intended to be an exhaustive list of all job duties for any one position in the class. Since class specifications are descriptive and not restrictive, incumbents can complete job duties of similar kind not specifically listed here.
