In addition, the problem of self-resonant frequency listed under the primary
inductance test also applies when measuring leakage inductance, so always use
the lower of the available band of frequencies.
User Offset
This is used to offset the result returned by the AT by a user defined amount.
i.e.
Result returned = Measured result + User offset
Normally a user offset would not be required. However, for small values of
leakage inductance (<1H) when there are many additional low terminals, it is not
always possible during fixture compensation for the tester to remove all the
parasitic errors of the test fixture. In this case, the user offset may be required to
fully remove the errors.
