Precision instrument assembler

Also called meter tester, gauge tester, meter assembler

Precision instrument assemblers read blueprints and assembly drawings to assemble precision instruments such as micrometers, gauges, thermostats and utility meters. They collect the different components and piece them together using hand tools or machinery. Furthermore they calibrate the instruments and test their precision.
