If a digital multimeter is set up as shown in figure "A" of the illustration, what would be displayed on the screen if the fuse being tested is not blown and has proper continuity? See illustration EL-0210.
• How a digital multimeter indicates an open circuit versus a closed circuit when set to the ohms (Ω) / continuity position • What a good fuse represents electrically (very low resistance path) compared to a blown fuse (open circuit) • Typical multimeter display of OL and what that means in resistance measurements
• Look at how the meter dial is set in figure A. Is it measuring voltage or resistance/continuity? • For a fuse that is intact, should the resistance be very high, very low, or somewhere in the middle? How would each of those look on a digital meter display? • Which answer choices correspond to an open circuit reading, and which correspond to a near‑zero resistance reading?
• Confirm the dial is on the ohms / continuity setting, not on any voltage range • Recall that OL on an ohms range usually means over limit / open circuit (no continuity) • Remember that a good fuse should have very low resistance from one end to the other, effectively acting like a piece of wire
