The LCR-Reader Ring Coil Tester is used with LCR-Reader-MPA for finding short turns in coils. These short turns are near impossible to detect using an LCR-meter as the impedance value may not change.
The LCR-Reader Ring Coil tester connects to LCR-Reader-MPA
through the micro-USB port; the hook connectors connect to the investigated coil. The MPA device must be set to "Winding Turns" in the menu. The MPA screen will show the excitation of the connected coil. A short turn will display a higher dissipation factor and therefore fewer oscillations following the impulse on the coil.
