Air-cored coils can pick up noise very easily,
therefore they should be kept well clear of any test
equipment that may contain power transformers
or display scan circuitry. Also, keep the coils away
from metal objects which may modify inductor
characteristics.
Iron-cored and
ferrite inductor
The effective value of iron-cored and ferrite
inductors can vary widely with the magnetization
and test signal level. Measure them at the AC level
and frequency in use. When core materials are
damaged by excessive magnetization (for
example: tape heads and microphone
transformers), check that the test signal is
acceptable before connection.
