E9-4 Q meter E9-4

E9-4

For order is possible effectively delivery of any quantity.
Meter Q E9-4 (E94, E-9-4, E 9 4, E-94, E 94)
 
Meter Q-E9-4 is designed to measure self-indicating an effective Q-factor inductors.
The device also is widely used to measure the capacitance and dissipation factor of capacitors, inductors coils, etc.
Q is counting on a scale pointer device. Q-factor is determined by the maximum deflection during pre-install it on the calibration label the scale.
