In which situation would an analog VOM be preferred over a DMM?

An analog Volt-Ohm Meter (VOM) is preferred in situations where intermittent fluctuations in a signal need to be observed. This preference arises from the analog meter's needle movement, which responds in real-time to changes in the voltage or current being measured. The smooth, continuous motion of the needle allows a technician to visually perceive rapid changes or fluctuations more effectively than a Digital Multimeter (DMM), which may display the value in a digitized format that could lag or miss quick transient changes.

In scenarios where signals are fluctuating rapidly, the analog VOM provides immediate visual feedback, allowing the technician to identify the peak and valley points of the signal during measurement. This dynamic response is particularly useful in troubleshooting and diagnosing circuits that have unstable or varying characteristics.

Other options, such as measuring high currents, digital signals, and low resistance readings, do not specifically leverage the unique strengths of an analog VOM compared to a DMM, which can often handle these tasks with better precision and display capabilities. Therefore, for applications focused on transient or intermittent signals, an analog VOM is distinctly advantageous.
