Occupations | Performs variety of electronic, mechanical, and electromechanical tests on electronic systems, subassemblies, and parts to ensure unit functions according to specifications or to determine cause of unit failure, using electronic test instruments: Reads test schedule, work orders, test manuals, performance specifications, wiring diagrams, and schematics to determine testing procedure and equipment to be used. Tests functional performance of systems, subassemblies, and parts under specified environmental conditions, such as temperature change, vibration, pressure, and humidity, using testing devices, such as temperature cabinets, shake-test machines, and centrifuges. Calibrates test instruments according to specifications. Connects unit to be tested to test equipment, such as signal generator, frequency meter, or spectrum analyzer. Reads dials or digital displays that indicate electronic characteristics, such as voltage, frequency, distortion, inductance, and capacitance. Compares results with specifications and records test data or plots test results on graph. Analyzes test results on defective units to determine cause of failure, applying knowledge of electronic theory and using electronic test equipment. Replaces defective wiring and components, using handtools and soldering iron, or records defects on tag attached to unit and returns unit to production department for repair. Confers with engineers, technicians, production personnel, and others regarding testing procedures and results and to resolve problems. May write computer programs to control semiconductor device and electronic component test equipment prior to testing, utilizing knowledge of programming techniques, electronics, test equipment, and testing specifications. May explain and demonstrate testing procedures to other workers. May verify dimensions of pins, shafts, and other mechanical parts, using calipers, vernier gauges, and micrometers. May operate x-ray equipment to verify internal assembly and alignment of parts according to specifications. May devise test equipment setup to evaluate performance and operation of nonstandard or customer returned units. May be designated according to unit tested as Memory-Unit Test Technician (electron. comp.); Television-Receiver Analyzer (electron. comp.); Transmitter Tester (electron. comp.); Tube-Test Technician (electron. comp.).

| Prepares specifications for fabrication, assembly, and installation of apparatus and control instrumentation used to test experimental or prototype mechanical, electrical, electromechanical, hydromechanical, or structural products, and conducts tests and records results, utilizing engineering principles and test technology: Confers with engineering personnel to resolve fabrication problems relating to specifications and to review test plans, such as types and cycles of tests, conditions under which tests are to be conducted, and duration of tests. Fabricates precision parts for test apparatus, using metalworking machines such as lathes, milling machines, and welding equipment, or interprets specifications for workers fabricating parts. Examines parts for conformance with dimensional specifications, using precision measuring instruments. Coordinates and participates in installing unit or system to be tested in test fixtures, connecting valves, pumps, hydraulic, mechanical or electrical controls, cabling, tubing, power source, and indicating instruments. Activates controls to apply electrical, hydraulic, pneumatic, or mechanical power and subject test item to successive steps in test cycle. Monitors controls and instruments and records test data for engineer's use. May recommend changes in test methods or equipment for engineering review. Workers are classified according to engineering specialty or type of product tested. (references) | |
| Inspects and tests storage batteries in process of manufacture or before shipment to verify conformity with mechanical, chemical, and electrical specifications, using specified and standardized tests, procedures, and equipment and applying knowledge of battery performance, specifications, manufacture, and construction: Disassembles batteries following specified procedures. Examines battery for defects and measures battery to determine if specifications are met, using such instruments as gauges and scales. Tests specific gravity of battery acid, using hydrometer and thermometer. Places battery in water tank or refrigerator to control temperature and test electrical capacity of battery. Attaches leads to meters and equipment to charge or discharge battery as specified to determine amperage delivered at given rate. Records inspection and test results, compares results with specifications, and writes reports used in correcting manufacturing defects or developing new products. May test and disassemble returned batteries to determine cause of failure. (references) | |
| Tests experimental and production agricultural equipment, such as tractors and power mowers and components to evaluate their performance, using test equipment and recording instruments: Reads data sheet denoting operating specification for unit or component and type of evaluation required. Tests unit for conformance with operating requirements, such as resistance to vibration, specified horsepower, and tensile strength and hardness of parts, using test equipment, such as bend-fatigue machine, dynamometer, strength tester, hardness tester, analytical balance, and electronic recorder. Records data from dial readings and graphs and computes values, such as horse-power and tensile strength, using algebraic formulas. Operates unit to evaluate attachment performance, such as depth of tillage or harvesting capabilities for different types of crops. Draws sketches and describes test procedures and results in test data log. (references) | |
| Administers and scores psychological, vocational, or educational tests: Distributes test blanks or apparatus to individuals being tested. Reads directions orally from testing manual, or gives other standardized directions. Demonstrates use of test apparatus or discusses practice exercises to familiarize individuals with testing material. Monitors test group to ensure compliance with directions. Times test with stop watch or electric timer. Scores test with test-scoring key or machine. May schedule time and place for test to be administered. May administer test designed to measure work skills of mentally or physically handicapped individuals. Records results on test paper, work application, or test profile form. (references) | |
