• If meter is not auto ranging, set it to the correct range
(See multimeter’s operation manual)
• Use firm contact with meter leads
• First test meter and leads by touching leads together.
Resistance should read a short circuit (very low resis-
tance)
• 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
