What is used to measure the output of electrical systems in maintenance?

In electrical maintenance, a multimeter is an essential tool used to measure a variety of electrical parameters, making it particularly versatile for assessing the output of electrical systems. A multimeter can measure voltage (volts), current (amperes), and resistance (ohms), allowing technicians to evaluate the electrical performance of circuits and identify any issues that may be affecting the system.

The multimeter combines the functions of voltmeters, ammeters, and ohmmeters into a single device, enabling maintenance personnel to perform comprehensive diagnostics without needing multiple tools. This flexibility makes it easier to troubleshoot electrical problems, ensuring that systems operate efficiently and safely.

In contrast, while an amperage meter and a voltmeter serve specific roles in measuring current and voltage respectively, they do not provide the breadth of measurements that a multimeter can. Additionally, a pressure gauge is irrelevant in this context as it measures pressure, not electrical output, and is used in fluid systems rather than electrical systems.
