What does a multimeter NOT measure directly?

A multimeter is a versatile instrument that can measure various electrical properties, including current, voltage, and resistance. However, it does not measure frequency directly.

When using a multimeter, it can be set to measure alternating current (AC) or direct current (DC) to determine the current values, typically found by placing the meter in series with the circuit. For voltage, it can be connected in parallel to measure the potential difference across components. Resistance, or ohmic values, is also directly measurable by the multimeter by sending a small current through the resistor and calculating its resistance based on Ohm's law.

In contrast, frequency measurement is not a direct function of a typical multimeter. Although some advanced multimeters may have a frequency measurement function, in general practice, standard multimeters do not directly measure frequency. Instead, specialized equipment such as frequency counters or oscilloscopes is used to obtain frequency readings.

This distinction is crucial in understanding the capabilities and limitations of the tools used in electrical diagnostics and testing.
