Which of the following statements about voltage testing is true?

A multimeter is indeed better than a voltage tester for troubleshooting because it is a more versatile tool, capable of measuring not just voltage but also current and resistance. This multifunctional capability allows technicians to diagnose and analyze electrical circuits more effectively. In troubleshooting scenarios, being able to measure different electrical parameters can provide a deeper insight into the system's health than simply knowing the presence or absence of voltage.

While a voltage tester is useful for quickly checking voltage levels, it does not provide the detailed information that a multimeter can offer. For example, a multimeter can give exact voltage readings and can help in determining electrical continuity, resistance levels, and current flow, which are essential in diagnosing issues in HVACR systems. This additional information can lead to a more precise identification of problems, making the multimeter the preferred choice for thorough troubleshooting.

In contrast, other options present incorrect statements. A voltage tester cannot measure current, as it is designed solely to indicate the presence of voltage. Similarly, a multimeter is specifically designed to measure voltage, making the assertion that it cannot measure voltage false. Lastly, stating that a voltage tester is always more accurate than a multimeter is misleading, as accuracy depends on the quality of the tools being compared rather than their type.
