Overview

A Metrology Technician calibrates high-precision electronic, mechanical, physical, optical, infrared, and laser test, measurement, and diagnostic equipment using higher-order measurement standards. The technician manages laboratory quality assurance, maintains calibration traceability and records, conducts audits and inspections, evaluates procedures and environmental conditions, and trains other calibration personnel and equipment users.

Core Skills

  • Calibration traceability to higher-order laboratory standards
  • Laboratory audits and quality verification inspections
  • Environmental impact assessment for calibration results
  • Defective calibration standard impact assessment

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Electrical and Electronic Engineering Technologists and Technicians

Precision electronic calibration, automated test-set work, and technical review of measurement procedures transfer to electronic equipment testing.

How to prepare: Complete a hands-on electronics troubleshooting project that uses schematics and test equipment to diagnose a fault and verify the repair.

What the civilian work involves
  • Set up and operate specialized or standard test equipment to diagnose, test, or analyze the performance of electronic components, assemblies, or systems.
  • Identify and resolve equipment malfunctions, working with manufacturers or field representatives as necessary to procure replacement parts.
Civilian tools and software (examples)
  • Microsoft Excel

Quality Control Analysts

Laboratory quality inspections, calibration problem-report review, and assessment of factors affecting measurement results transfer to equipment validation and test-data review.

How to prepare: Choose a target industry's laboratory test procedure and practice comparing its results with specifications and control limits, focusing on unfamiliar sample-analysis methods.

What the civilian work involves
  • Interpret test results, compare them to established specifications and control limits, and make recommendations on appropriateness of data for release.
  • Calibrate, validate, or maintain laboratory equipment.
Civilian tools and software (examples)
  • Microsoft Excel
