Your calculation is wrong - sorry! Offtopic : This formula is easily derived by using the complex .

This simple technique provides surprisingly good accuracy and wide dynamic range, therefore it can be implemented in almost any DMM , without significant cost penalties.

There are other techniques as well.

In this article, we will go over one main way to measure the inductance of an inductor or any device, and this is done by using an inductance meter. The first is to place the inductor in series with . This accuracy is sufficient for many applications such as the starting circuit for an electric motor or for power supply filtration. Measuring arrangement: resonance measurement. Though it heavily depends on the gauge and length of the wire, I would say, Ohm makes sense.

Turn on the oscilloscope and clamp the two clips of one voltmeter to the circuit on opposite sides of the coil to determine the voltage drop across the coil. Then do the same for the resistor with another voltmeter. Set the frequency of the oscilloscope such that the voltage drop across the resistor and inductor . In the simpler versions of this instrument the impedance was measured internally and converted for display to the corresponding capacitance or inductance value.

DMM Digital Multimeter with LC Inductance Capacitance and Frequency. A simple test to find the magnetic permeability of an inductor core. Sorry to butt in, but it seemed like an appropriate threa and it appears to be done with. If you ever wondered how this can be accomplishe here you go. You can expect capacitance and inductance values with - . NOTE: actually, this will not generally work as expected for iron core transformers because of hysteresis effects that will fake out the meter).

Measure the inductance of each winding with all . Put an ohmic resistor in series with inductor and measure the tension over the resistor. Hz ( depends on region you live), doing so will create some error but are generally within acceptable range. Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters.

The phenomenon of LC resonance based on the inductance of inductors (or coils ) and the parasitic capacitance of coils is known as self-resonance, and the frequency at which self-resonance occurs is known as the self-resonant frequency. Do not use the meter if the meter or test leads look damage or if you suspect that the meter is not operating. For loops multimeters will check continuity, but will not tell you if . LCR meters are used to measure the.
