When compared to an electronic digital voltmeter, the main disadvantage of the Simpson 250 analog multimeter is which of the following?

Correct Answer: Option A — Tends to "load" the circuit being tested.

Analog multimeters like the Simpson 250 have lower ohms-per-volt sensitivities than digital meters, drawing operating current from the circuit under test. This additional current draw alters circuit conditions, a phenomenon known as meter 'loading,' introducing measurement errors on sensitive marine electronics.
