Quality factor measuring E4-11 (E411, E-4-11, E 4 11, E-411, E 411)

Quality factor measuring E4-11 provides a measurement of the effective Q inductive character objects, as well as their self-capacitance and the resonant frequency of the circuit. By indirect measurements can determine the inductance of the measured object, the capacity, the amount of dissipation factor of capacitors, two-terminal resistance.
The operation principle E4-11 based on the resonance voltage in the series resonant circuit.
Q counting on a scale galvanometer. Q-factor is determined by the maximum deflection of the needle during pre-install it on the calibration mark of the scale.
