Continuity and Low Resistance Testing
No electrical test is simpler...and few more commonly employed…than the continuity test. This simple test is a ubiquitous option on multimeters (DMMs) and insulation testers. It is simple to perform; connect two leads across opposite ends of the test item (IUT), press the test button, and within seconds you have the resistance reading. Low is good, high is bad. It’s so simple and easy that it is readily applied to testing situations that require a more rigorous performance from the test instrument. This article will examine the parameters that determine the separation between the types of instrumentation.
