Continuity testers are electrical test instruments that are used to determine if an electrical circuit exists between two points

Automated test equipment (ATE) is used to monitor and control test and measurement devices, keeping human interaction at a minimum

Backplane testers evaluate and record the integrity of printed circuit boards (PCBs) and passive component electronics such as resistors, capacitors, and diodes

Wire harness testers evaluate continuity, resistance, isolation, and other performance factors for multi-strand wire harnesses

Cable testers are handheld or benchtop electronic devices that measure the electrical and physical properties of network cabling

Voltage testers check for difference in potential in electrical circuits

Current leakage testers measure the amount of current that leaks to ground
