Resistance Measurement
•First test meter and leads by touching leads
together. Resistance should read a short circuit
(very low resistance)
•Circuit power must be turned OFF before testing
resistance
•Disconnect component from circuit before testing
•If meter is not auto ranging, set it to the correct
range (See multimeter’s operation manual)
•Use firm contact with meter leads
Continuity Measurement
•Some meters require a separate button press to
enable audible continuity testing
•Circuit power must be turned OFF before testing
continuity
•Disconnect component from circuit before testing
•Use firm contact with meter leads
•First test meter and leads by touching leads
together. Meter should produce an audible alarm,
indicating continuity
