Which of the following statements about voltage testing is true?

The statement that a multimeter is better than a voltage tester for troubleshooting is true. A multimeter offers versatility, as it can not only measure voltage (both AC and DC) but also test resistance and current, providing a more comprehensive analysis of electrical issues. This multifunctionality enables technicians to diagnose problems more effectively by giving more data about the circuit's characteristics.

Voltage testers, while simpler and quicker for basic checks, primarily indicate the presence or absence of voltage and may not provide the detailed information needed for thorough troubleshooting. This lack of functionality makes multimeters the preferred tool for diagnosing and troubleshooting electrical issues in HVACR systems.
