Zero the meter again for this range and repeat the step above. Consult the meter manual if you're unsure which jacks should be used. ![]() It is equally important to have the test leads connected to the proper jacks as it is to have the selector switch range and test type (volts, amps, ohms) set. Many meters have additional jacks that are required for current or high-voltage tests.This is nice to know when the circuit under test isn't labeled + or, as is usually the case. If the test leads were installed as suggested, the red lead would be positive as compared to the black test lead. The + and symbols represent the polarity of probes when set for and testing DC volts.The other jack or jacks should be labeled "V" (+) and the Omega symbol (an upside down horseshoe) for Volts and Ohms, respectively.It will be used for nearly every measurement taken. This is where the black test lead will be connected. One is usually labeled "COM" or (-), which stands for for common. ![]() ![]() Most multimeters have several jacks used for this purpose. Locate the openings in the case where you'll insert the test leads.
