Electrical/Electronics Maintenance and Repair Technologies/Technicians

Inspect, test, repair, or maintain electrical equipment in generating stations, substations, and in-service relays.

• Inspect and test equipment and circuits to identify malfunctions or defects, using wiring diagrams and testing devices such as ohmmeters, voltmeters, or ammeters.
• Prepare and maintain records detailing tests, repairs, and maintenance.
• Consult manuals, schematics, wiring diagrams, and engineering personnel to troubleshoot and solve equipment problems and to determine optimum equipment functioning.

Repair, test, adjust, or install electronic equipment, such as industrial controls, transmitters, and antennas.

• Test faulty equipment to diagnose malfunctions, using test equipment or software, and applying knowledge of the functional operation of electronic units and systems.
• Maintain equipment logs that record performance problems, repairs, calibrations, or tests.
• Set up and test industrial equipment to ensure that it functions properly.

Install, set up, rearrange, or remove switching, distribution, routing, and dialing equipment used in central offices or headends. Service or repair telephone, cable television, Internet, and other communications equipment on customers' property. May install communications equipment or communications wiring in buildings.

• Demonstrate equipment to customers and explain its use, responding to any inquiries or complaints.
• Test circuits and components of malfunctioning telecommunications equipment to isolate sources of malfunctions, using test meters, circuit diagrams, polarity probes, and other hand tools.
• Test repaired, newly installed, or updated equipment to ensure that it functions properly and conforms to specifications, using test equipment and observation.

Repair, install, or maintain mobile or stationary radio transmitting, broadcasting, and receiving equipment, and two-way radio communications systems used in cellular telecommunications, mobile broadband, ship-to-shore, aircraft-to-ground communications, and radio equipment in service and emergency vehicles. May test and analyze network coverage.

• Inspect completed work to ensure all hardware is tight, antennas are level, hangers are properly fastened, proper support is in place, or adequate weather proofing has been installed.
• Run appropriate power, ground, or coaxial cables.
• Test operation of tower transmission components, using sweep testing tools or software.

Install, program, maintain, and repair security and fire alarm wiring and equipment. Ensure that work is in accordance with relevant codes.

• Install, maintain, or repair security systems, alarm devices, or related equipment, following blueprints of electrical layouts and building plans.
• Mount and fasten control panels, door and window contacts, sensors, or video cameras, and attach electrical and telephone wiring to connect components.
• Demonstrate systems for customers and explain details, such as the causes and consequences of false alarms.

Repair, maintain, or install electric motors, wiring, or switches.

• Inspect and test equipment to locate damage or worn parts and diagnose malfunctions, or read work orders or schematic drawings to determine required repairs.
• Reassemble repaired electric motors to specified requirements and ratings, using hand tools and electrical meters.
• Measure velocity, horsepower, revolutions per minute (rpm), amperage, circuitry, and voltage of units or parts to diagnose problems, using ammeters, voltmeters, wattmeters, and other testing devices.

Install, repair, or adjust audio or television receivers, stereo systems, camcorders, video systems, or other electronic entertainment equipment in homes or other venues. May perform routine maintenance.

• Install, service, and repair electronic equipment or instruments such as televisions, radios, and videocassette recorders.
• Calibrate and test equipment, and locate circuit and component faults, using hand and power tools and measuring and testing instruments such as resistance meters and oscilloscopes.
• Confer with customers to determine the nature of problems or to explain repairs.

Repair, maintain, or install computers, word processing systems, automated teller machines, and electronic office machines, such as duplicating and fax machines.

• Reassemble machines after making repairs or replacing parts.
• Converse with customers to determine details of equipment problems.
• Disassemble machines to examine parts, such as wires, gears, or bearings for wear or defects, using hand or power tools and measuring devices.
