Which disadvantage do digital multimeters eliminate compared to analog meters?

Digital multimeters (DMMs) are designed to provide precise numerical readings without the user having to interpret a dial or scale, which is a feature of analog meters. One significant disadvantage of analog meters is the occurrence of parallax errors. Parallax errors arise when the scale reading is viewed from an angle rather than directly in line with the pointer, leading to inaccuracies in reading the measurement.

In contrast, digital multimeters display measurements in a straightforward numerical format on an LCD or LED screen, eliminating the possibility of reading angle-induced errors. This clarity allows users to obtain accurate readings quickly and without misinterpretation. Additionally, DMMs have higher input impedance, which reduces the loading effect on the circuit being measured, and they often offer better accuracy compared to the typical analog meter.

While low impedance and poor accuracy are considerations that can be better handled by digital meters, the unique ability of DMMs to avoid parallax errors makes this aspect particularly noteworthy. Thus, the elimination of parallax errors is a clear advantage of digital over analog meters.
