Test equipment is a general term describing equipment used in many fields. Types of test equipment include:

• Battery tester, used to test the state of an electric battery
• Continuity tester, used to determine if an electrical path can be established between two points
  • Cable tester, used to verify the electrical connections in a signal cable or other wired assembly
  • Receptacle tester, used to verify that an AC wall outlet is wired properly
  • Test light, used to determine the presence or absence of an electric voltage
• Hipot tester, used to verify electrical insulation in finished products carrying high electrical potential

Electronic test equipment is used to create signals and capture responses from electronic devices, to prove proper operation or trace faults. Types of electronic test equipment include:

• Automatic test equipment, any apparatus that performs tests using automation
• Built-in test equipment, passive fault management and diagnosis equipment built into airborne systems to support maintenance
• On-board diagnostics, test equipment for automobiles
• Transistor tester, used to test the electrical behavior of transistors and solid-state diodes

• Adhesion tester, used to determine if a paint or coating will adhere properly to a substrate
• Brake tester, used to calculate the braking efforts and efficiencies of a motor vehicle
• Deadweight tester, a calibration tool for pressure gauges
