I am not going to explain how to operate your LCR meter. That is the manufacturer's job. I will try to explain electrical impedance. Impedance does not make sense unless you are dealing with sinusoidal functions. A sinusoid is the the only continuous periodic function that retains its shape after passing through a linear RCL network. Impedance is a complex number, specifically a duplex number containing a real part and an orthogonal component usually misnamed the "imaginary" part.
The components of impedance are resistance and reactance. Both those impedance constituents impede current, but they do it in different ways. Perfect resistors impede current by dissipating the electrical energy as heat, thereby reducing the voltage after the charge flow passes through the resistor. Remember, voltage is the energy density of the unit charge,so if energy is wasted as heat, the energy density of the charges will be less and the voltage will drop. A perfect inductor produces a back voltage that lowers the applied voltage so that less current is present in the inductor. This does not dissipate energy and produces no heat. Instead the energy is stored in a magnetic field during part of the sinusoidal period and released back into the circuit later in the period. A perfect capacitor also produces a back voltage and stores energy is a electric, not a magnetic field. This, too, produces no heat or energy loss. In a perfect inductor, the current lags the voltage by 90°, and in a perfect capacitor, the current leads the voltage by 90°. Therefore, inductive and capacitive reactance cancel each other out. The impedance is the absolute value of the complex total of the resistance and the reactance in an orthogonal (90°) orientation.
To find the impedance of a circuit containing more that one component, you have to be cognizant as to how the components are hooked up (series or parallel). That will make a big difference on what the impedance value will be.
Time for you to ask some questions.
