When adjusting an analog meter for resistance measurement, what does a "0 Ω" reading indicate?

A "0 Ω" reading on an analog meter when measuring resistance indicates that there is a direct electrical connection across the probes of the meter, meaning that the circuit or component being tested has zero resistance. This generally suggests that the meter is functioning correctly, as it demonstrates that it can detect and measure the resistance accurately. Zero resistance indicates a complete path for current to flow, which is characteristic of a good conductor or a short circuit in the case of wires or connections.

In contrast, other readings would indicate different conditions: a broken meter would not provide any readable resistance measurement, an energized circuit would produce misleading readings due to the presence of voltage, and an infinite resistance would imply an open circuit where current cannot flow at all. Therefore, only a "0 Ω" reading confirms the meter's proper function and the integrity of the connections being tested.
