It uses Impedance technique. Check Out some LCR meter data sheets such as Agilent user manual it has a break down on the measurement principles or search for books on instrumentation and measurement which explain the actual circuit diagram.
Q-meter works on the principle of Series Resonance
transformer works induction principle
the principle on which an electromagnetic crane works is electromagnetic induction
trivector meters are used to measure kVAh and also kVA of maximum demand.it has a kwh meter and reactive kvah meter in a case with special summator mounted between them.
It is a special type of synchronous motor.It works on the principle of hysteresis and the torque is produced due to hysteresis

LCR meter is a device. And electrochemical impedance spectroscopy is a method. So the difference between them are like the difference between pen and writing.
The LCR meter was invented by Howard Cary in 1924 while working for General Radio Company. The instrument was initially developed for measuring electrical properties including inductance, capacitance, and resistance.
Self resonant frequency.
You can use a LCR (Inductance, Capacitance, Resistance) meter if you can find one.
An LCR meter measures the inductance (L), capacitance (C), and resistance (R) of electronic components. It applies an alternating current (AC) signal to the component and analyzes the resulting voltage and current phase shift to calculate the component's values. By using precise frequency and measurement techniques, the LCR meter provides accurate readings of the component's impedance, allowing for the assessment of its performance in circuits. Some advanced LCR meters can also measure parameters like quality factor and dissipation factor.
LCR meters measure inductance capacitance and resistance Q requires 2 at once and probably a frequency range you may care about q meter will probably have two readouts and you may be able to change from Q to power factor
LCR meters measure inductance capacitance and resistance Q requires 2 at once and probably a frequency range you may care about q meter will probably have two readouts and you may be able to change from Q to power factor
L = Inductance, C = Capacitance, R = Resistance & Q = Frequency.
