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

🔍 Key Concepts

• Analog vs. digital meters – how the display type affects accuracy and reading error • Input impedance (circuit loading) – how much the meter itself affects the circuit being measured • Typical accuracy and resolution differences between a Simpson 250 analog multimeter and a modern digital voltmeter

💭 Think About

• Ask yourself: Does an analog meter usually disturb the circuit more or less than a modern digital meter, and why? • Think about which type of meter generally gives more precise and repeatable readings: classic analog or modern digital? • Consider what the word "load" means in an electrical circuit and how a meter with lower input resistance would affect that circuit.

✅ Before You Answer

• Verify which type of meter typically has higher input impedance (resistance) – this usually loads the circuit less. • Compare the specified accuracy (percent of full scale or reading) for a Simpson 250 analog meter versus a typical digital voltmeter. • Be sure you understand that "loading the circuit" means the meter is drawing current and thereby changing the voltage you are trying to measure.

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

Tends to "load" the circuit being tested.

Has a greater margin of error.

Has a less margin of error.

Tends to "unload" the circuit being tested.
