What types of measurements can a multimeter perform?

A multimeter is a versatile instrument commonly used in electrical and electronic work for a variety of measurement tasks. It can measure voltage, which refers to the electrical potential difference between two points; current, which is the flow of electric charge measured in amperes; and resistance, which indicates how much the material opposes the flow of electric current and is measured in ohms.

The ability to perform these three functions makes a multimeter an essential tool for technicians, allowing them to troubleshoot and diagnose issues with electrical equipment effectively. For example, measuring voltage can help determine if a device is receiving the proper power supply, while measuring current can help assess whether a circuit is functioning correctly. Resistance measurements are critical for testing components like resistors and ensuring they are operating within their specified limits.

By offering multifunctionality, the multimeter streamlines the process of electrical testing, reducing the need for multiple tools and promoting efficiency in maintenance and repair tasks. Thus, the correct understanding of a multimeter's capabilities is crucial for anyone working with biomedical equipment and electronics.
