Continuity checks are typically performed on a variety of devices, including cable assemblies, printed circuit boards, and connectors, to ensure these components have a continuous path where desired.
Examples of insulation resistance measurements include measuring the path be tween traces on a printed circuit board or the resistance between conductors in a multi-conductor cable.
