What does it imply when an analog meter displays a reading outside its expected range?

When an analog meter displays a reading outside its expected range, it indicates that there could be potential problems either with the meter itself or with the circuit it is measuring.

If the meter is functioning properly, readings outside the expected range typically suggest a fault in the circuit, such as a short circuit, an open circuit, or other anomalies that affect electrical flow. This can lead to the meter indicating values that do not accurately represent the actual conditions of the circuit.

On the other hand, there is also the possibility that the meter itself is malfunctioning. Analog meters can develop faults over time, such as a sticky needle, calibration issues, or damage, which would cause incorrect readings outside the normal range.

Combining these factors, both the possibility of a circuit issue and a meter malfunction are valid interpretations when encountering unexpected meter readings, confirming that both scenarios should be investigated. Therefore, identifying that both explanations (the meter may be malfunctioning and a circuit issue may exist) are plausible leads to the conclusion that both assessments are essential when troubleshooting.
