Gas Fitter Practice Test

For what purpose is a multimeter primarily used?

1. Measuring temperature

2. Measuring voltage, current, and resistance

3. Testing for continuity

4. All of the above

The correct answer is: Measuring voltage, current, and resistance

The primary purpose of a multimeter is to measure voltage, current, and resistance, making it an essential tool for electricians and technicians. A multimeter can be used to verify if circuits are functioning correctly, troubleshoot electrical problems, and ensure safe electrical installations by providing accurate readings of these key electrical parameters. While continuity testing is indeed a common function of a multimeter, the broader and primary functions are focused on measuring voltage, current, and resistance, which are fundamental for diagnosing and working on electrical systems. Other measuring devices or specialized thermometers are typically used to measure temperature, which is outside the scope of a multimeter's primary functions. Thus, while multimeters can perform multiple tasks, their core utility lies primarily in measuring voltage, current, and resistance.
