What equipment is commonly used to measure voltage in a circuit?

The clamp-on multimeter is commonly used to measure voltage in a circuit because it is designed for both current and voltage measurements. It can easily measure the voltage across a circuit without the need for direct contact with the circuit elements, making it user-friendly and safe.

This versatility allows technicians to diagnose electrical issues efficiently while minimizing disruption to the system being tested. It typically features a display that shows the voltage reading directly without the need for additional probes or complex setups.

In contrast, while an oscilloscope can also measure voltage, it is primarily utilized for observing the waveform of electrical signals, making it a more complex tool for basic voltage measurements. A function generator is used to create electrical waveforms and is not designed for measurement purposes. An insulation tester is specialized for testing the integrity of insulation in electrical devices and isn’t intended for general voltage measurement in live circuits.
