3300 — INSTRUMENT WORK FAMILY
This job family includes occupations that involve fabricating, assembling, calibrating, testing, installing, repairing, modifying, and maintaining instruments and instrumentation systems for measuring, regulating, and computing physical quantities such as mass, moment, force, acceleration, displacement, stress, strain, vibration or oscillation frequency, phase and amplitude, linear or angular velocity, spacetime position and attitude, pressure, temperature, density, viscosity, humidity, thermal or electrical conductivity, voltage, current, power, power factor, impedance, and radiation. Examples of such instruments and equipment are: gyro, optical, photographic, timekeeping, electrical, metered, pressure, and geared instruments; test equipment; and navigation, flight control, and fuel totalizing systems. The work requires knowledge of electrical, electronic, mechanical, optical, pneumatic, and/or hydraulic principles. Work that primarily involves fabricating and repairing electronic instruments should be coded to the electronic equipment installation and maintenance family, 2600.
