    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.

Throughout the following information, an asterisk (*) stands for series with a published standard and a double asterisk (**) stands for series with a published flysheet.

Occupations in this family are:

3306 Optical Instrument Repairing *

This occupation includes jobs involved in troubleshooting, overhauling, modifying, maintaining, and testing optical instruments such as binoculars, telescopes, cameras, sextants, gunsights, periscopes, and cinetheodolites. These jobs primarily require knowledge and application of optical principles, procedures, and materials and, in addition, knowledge of mechanical and electrical methods of mounting and controlling optical systems.

3314 Instrument Making *

This occupation includes jobs involved in planning and fabricating complex research and prototype instruments that are made from a variety of materials and are used to detect, measure, record, and regulate heat, pressure, speed, vibration, sound, illumination, biomedical phenomena, and other areas of interest to scientific, engineering, or medical personnel. The work requires skill and knowledge of more than one specific trade.

3359 Instrument Mechanic *

This occupation includes jobs involved in troubleshooting, repairing, overhauling, modifying, testing, calibrating, and installing mechanical, electrical, electronic, and/or pneumatic instruments, electronic components and assemblies, test equipment, and functionally related assemblies, automated equipment, timekeeping instruments, and controls related to the operation of industrial, power generation, airborne, marine, and precision measurement equipment and systems. The work includes the repair, maintenance, and calibration of precision measurement instruments and standards such as flow stands, test consoles, recorders, analyzers, converters, and other general and special purpose test equipment. The work requires knowledge and application of mechanical, electrical, and electronic principles, procedures, and materials; knowledge of the pneumatic and hydraulic mechanisms used to convert pressure and flow into measurable units; and knowledge of the basic operating principles of electronics.
