The standard unit of measurement for electrical capacitance.

Diagnosing

A troubleshooting step where a technician collects as much information as possible about the system, circuit, and components used.

Good Troubleshooting

A logical and orderly procedure used to solve technical issues.

Shorted Capacitor

A defect indicated when an ohmmeter shows no resistance or $0\text{ ohms}$ during capacitor testing.

Open Resistor

A defect indicated when an ohmmeter shows very high or infinite resistance across a resistor.

Soldering

A process where two or more metal items are joined together by melting and flowing a filler metal into the joint.

Component Testing

A method of testing the lowest or smallest unit of an application (also referred to as Program or Module Testing) to look for bugs and validate functioning.

Work Orders

Administrative documents used to request, assign, and track work accomplished by facilities operations for maintenance, repair, and minor construction.

Multi-Tester

A multi-function instrument that can serve as an ohmmeter, voltmeter, or ammeter.

Corrective Action
