• Understand calibration sheets, instrument specification sheets and installation details. Recognize standard symbols.
• Understand and recognize electrical and electronic units of measurement such as volts, amps, watts, ohms, hertz, farads, etc.; basic components (batteries, voltage sources, current sources, resistors, capacitors, inductors, transistors and integrated circuits).
• Be able to apply the principles of pneumatics as used in industrial instrumentation.
• Understand the terminology (PSIG, PSIA, supply air, instrument air, signal); components (links, levers, flapper or baffle, nozzle, relay, vents, filters); and pneumatic circuitry.
• Must possess the knowledge to understand current-voltage-resistance relationships in direct current circuits. Apply Ohm’s Law.
• Must possess the knowledge to understand current-voltage-impedance relationships in alternating current circuits.
• Understand basic trouble shooting methods for motors, contactors, transformers, relays, and lighting. Recognize power quality problems.
• Read and interpret wiring and ladder diagrams.
• Possess the ability to understand the operation of basic electric/electronic test equipment (DC power supplies, milliamp calibrators, millivolt calibrators, multimeters, signal sources, function generators, oscilloscopes, decade boxes, Wheatstone bridges, impedance testers and frequency generators); calibration procedures for electric and electronic transmitters, controllers and control valve actuators; bench repair of various electric and electronic instruments and components (circuit boards, power supplies, relays, receiver and transmitter elements).
• Inspect and replace power cords and distribution cables. Locate and replace faulty resistors, capacitors, inductors, transistors, IC units and printed circuit (PC) boards.
• Use appropriate test equipment, soldering techniques, wire wrap techniques, hand tools, component and wire identification documentation.
• Understand the types of pneumatic and electronic transmitters used in level measurement, the calibration of each and the test instruments used.
• Connect pneumatic and electronic level sensors and transducers for accurate calibration.
• Install and maintain truck loading, additive injection, and pipeline proving and control systems (where applicable).
• Should poses a basic understanding of Cathodic Protection.
