A direct-reading instrument formerly widely used to measure the Q of an electrical component or passive network of components at radio frequencies. The instrument measures the voltage applied to a component or circuit together with the voltage across a key component and calculates the Q of the circuit from their ratio. An impedance-measuring instrument (bridge or analyzer) is more likely to be employed now. See also: Electrical measurements; Q (electricity); Radio-frequency impedance measurements
