When testing continuity with a digital multimeter, what does OL on the display typically indicate?

• A. Continuity
• B. OL
• C. 1
• D. 0

Answer: (B)

When you test continuity with a digital multimeter, the meter applies a small current between the probes to see if a complete path exists. If there is a good conductor between the probes, you’ll typically see a very low resistance and often hear a beep. If the display shows OL, that means the resistance is beyond the meter’s measurable range—in other words, there is no complete path between the probes, i.e., an open circuit or a broken connection. OL signals that continuity does not exist, not that there is a specific low or high fixed value.
