Why Do Almost No Digital Multimeters Measure Inductance?
Most digital multimeters do not measure inductance because it requires a specialized measurement function and specialized circuitry. Measuring inductance typically requires the application of an AC voltage signal at a known frequency, followed by measurement of the resulting AC current, and calculation of the inductance based on the ratio of voltage to current. This type of measurement is typically performed with an LCR meter, which is a specialized instrument designed specifically for measuring inductance, capacitance, and resistance.
While some digital multimeters do include an inductance measurement function, it is generally not as accurate as a dedicated LCR meter and is intended for basic measurements only. For more precise measurements or for measuring inductance in a high-frequency circuit, an LCR meter is typically recommended.
