Why would one prefer a digital VOM over an ordinary analog meter?

Choosing a digital volt-ohm meter (VOM) over an analog meter primarily revolves around the increased accuracy that digital models provide. Digital meters use a numerical display that can show values with a higher degree of precision compared to the needle on an analog meter, which can be difficult to read accurately due to parallax errors and the subjective interpretation of the scale.

Moreover, digital meters often have features that enhance their functionality, such as automatic ranging, which allows the meter to select the most appropriate range for measurements, reducing the chance of user error caused by incorrect range settings. These factors combined make digital VOMs a preferred choice for those requiring reliable and precise readings in electronic measurements.

While factors such as size, cost, and measurement capabilities may influence a user's decision, the clarity and reliability of the measurement, particularly in intricate and sensitive applications, solidify the preference for digital meters in many professional and educational settings.
