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
Q-meter works on the principle of Series Resonance
CLAMP METER WORKS WITH THE PRINCIPLE OF HALL EFFECT..
Series resonance
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.
Self resonant frequency.
You can use a LCR (Inductance, Capacitance, Resistance) meter if you can find one.
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.
basic principle of analogue clamp meter
