| For continuity checking, you will typically place the BLACK probe at one test location and the RED probe at another test location. With the meter set for continuity (this meter shows a buzzer symbol), the internal battery sends a voltage out of the meter to see if that voltage reaches the other probe - which would indicate continuity between the two probes. In continuity checking, the BLACK probe may not be connecting to ground or the negative battery post. Continuity checking is really a form of ohms resistance testing for nearly 0ohms (meaning little resistance) and very good conduction between the two test points. | For continuity checking, you will typically place the BLACK probe at one test location and the RED probe at another test location.

| When taking a typical reading, you will place the probes at two testing points (which may not include grounding). This measures the resistance to the voltage being sent out from the meter on one probe as it makes it's way to the other probe. For instance, you may be testing the resistance in the starter motor windings in order to see if there is a short circuit (shown as too low resistance) or testing the starter relay windings for shorts. Most of these type tests are expecting a small level of resistance even when functioning correctly, so it's important to have a low scale on your meter in order to properly see small differences. | When taking a typical reading, you will place the probes at two testing points (which may not include grounding).
