In a circuit, a similar diode should still indicate a forward bias reading of 0.5 V to 0.8 V; however, the reverse-bias reading can
vary depending on the resistance of other pathways between the probe tips.

continuity.
Continuity is the presence of a complete path for current flow. The continuity test features a beeper that sounds if a circuit is
complete. The beeper allows you to perform quick continuity tests without having to watch the display.
