The Winding Impedance with External Bias test measures the impedance of a
selected winding while applying a DC current from the DC1000 through the
winding. An AC voltage is also applied across the winding from the AT.
This test can be used with inductors to measure the change in impedance with
a bias current.
On selecting “ZBX Impedance with External Bias” from the ‘available tests’
window, the following dialog box is displayed:
