Question: 1 / 400

What condition can a multimeter help diagnose in electrical troubleshooting?

Physical damage to tools

Voltage deviation from expected values

A multimeter is a versatile tool that can diagnose various electrical issues, making it indispensable in troubleshooting. In the context of voltage deviation from expected values, a multimeter specifically measures voltage in circuits. When the measurement differs from the expected values, it can indicate problems such as an open circuit, a short, or faulty components that are responsible for the deviation. Understanding voltage levels is crucial for identifying whether equipment is operating within its designed specifications or if there are underlying issues affecting performance.

While a multimeter can provide insights into physical conditions in a circuit, such as poor connections and voltage issues, it does not diagnose physical damage to tools directly. Instead, it gives accurate readings that might suggest indirect problems, such as a tool not functioning properly due to issues in the circuit it is a part of. Thus, while voltage deviation is a clear diagnostic capability of the multimeter, the other options, while potentially relevant to troubleshooting, do not encapsulate the primary function of a multimeter in diagnosis as effectively as voltage measurement does.
