Model 4262A Section IV
Paragraph 4-13
PERFORMANCE TESTS
4-13. INDUCTANCE ACCURACY TEST.
DESCRIPTION:
This test verifies that inductance measurement accuracy satisfies the specifica-
tions listed below. L accuracy is proved to meet the specification when the results
obtained in the accuracy checks of paragraphs 4-9 through 4-12 satisfy the speci-
fications. This test is performed to confirm the L accuracy specification.
Note
Inductance accuracy has only to be proved
for one inductor of about full scale value on
any one range to verify specifications for all
three test frequencies (120Hz, 1kHz and
10kHz).
