WebTest with resistance mode: First, set the multimeter to resistance mode. Try to adjust it to the lowest possible readings. Secondly, connect the red and black probes to positive and … WebContinuity is the presence of a complete path for current flow. A closed switch that is operational, for example, has continuity. A continuity test is a quick check to see if a circuit is open or closed. Only a closed, complete circuit (one that is switched ON) has continuity. During a continuity test, a digital multimeter sends a small current ...
