Testing & TroubleshootingQuestion 497 of 521
Testing a suspected conductor with an ohmmeter, you read 'OL' (over-limit / infinite). What does this indicate about the conductor?
a.A dead short (0 ohms) between the leads
b.A perfectly good, low-resistance conductor
c.An open circuit, the path is broken (infinite resistance)
d.Exactly 1 megohm of resistance
Explanation
'OL' or an infinity display means resistance is beyond the meter's range, an open (broken) path with no continuity. A dead short reads near 0 ohms (a), a good conductor reads a very low value (b), and OL is not a specific finite value like 1 megohm (d).
