measurements (see the LS test) and compares the two results. Limits for the
match of the two measured inductances may be set in terms of the ratio
between them (e.g. 1:1 ±5%).
By adding further inductance match tests to the program any number of
inductances can be tested for match.
Choosing Test Conditions
For optimum accuracy and performance, use the test conditions shown in the
inductance section of this chapter for each of the two windings. The frequency
will be common to both windings being tested for match.
The test conditions can also be determined automatically by the ATi according
to this table:
