Q-Meter
The Q meter is an instrument used to measure electrical properties of coils and capacitors. Mostly used in testing the radio frequency circuits. A Q-meter basically measures the Q (Quality Factor) of the circuit. It is also used to test the inductors, capacitors for their high frequency inductance, Q , capacitance as well as ∑, tg δ value.
