A basic multimeter is generally designed to measure three fundamental electrical parameters: voltage, current, and resistance.

Voltage measurements can be taken in both alternating current (AC) and direct current (DC) modes, allowing the technician to assess the potential difference across electrical components. Current measurements also come in AC and DC forms, enabling the measurement of the flow of electric charge through a circuit. Resistance measurements help determine how much a component resists the flow of electric current, which is crucial for troubleshooting and ensuring the integrity of electrical circuits.

While capacitance is a valuable parameter to measure, basic multimeters typically do not include the capability to measure capacitance unless they are specifically designed with that function. Therefore, while capacitance and frequency can be measured by advanced multimeter models, they are not part of the standard features found in a basic multimeter.

This focus on the three key parameters – voltage, current, and resistance – is what makes this answer accurate for defining the capabilities of a basic multimeter.
