Industrial Maintenance Technician Practice Test

Question: 1 / 400

Which of the following tools is least effective for diagnosing electrical issues?

Volt-ohm tester

Multimeter

Hammer

The hammer is least effective for diagnosing electrical issues because it is not designed for measuring or analyzing electrical properties. While volt-ohm testers, multimeters, and oscilloscopes are specifically engineered to evaluate voltage, current, resistance, and various signal forms in electrical systems, a hammer serves a completely different function related to physical manipulation, such as driving objects or breaking materials. Therefore, when addressing electrical diagnosis, a hammer lacks the capabilities to provide necessary insights or readings that assist technicians in troubleshooting electrical problems, making it an ineffective tool for this purpose.
