Q meter

Q meter [′kyü ‚mēd·ər]

(engineering)

A direct-reading instrument which measures theQof an electric circuit at radio frequencies by determining the ratio of inductance to resistance, and which has also been developed to measure many other quantities. Also known as quality-factor meter.

Q meter

A direct-reading instrument widely used for measuring the Q of an electric circuit at radio frequencies. Originally designed to measure the Q of coils, the Q meter has been developed into a flexible, general-purpose instrument for determining many other quantities such as (1) the distributed capacity, effective inductance, and self-resonant frequency of coils; (2) the capacitance, Q or power factor, and self-resonant frequency of capacitors; (3) the effective resistance, inductance or capacitance, and the Q of resistors; (4) characteristics of intermediate- and radio-frequency transformers; and (5) the dielectric constant, dissipation factor, and power factor of insulating materials.
