Appendix B – Component Identification
It is important to appreciate that the
LCR40
can only decide on the identity of
the component under test using results of the electrical tests that it performs on
the component.
The
LCR40
determines the type of component under test according to the
following criteria:
Inductor and Resistor Detection
The
LCR40
will distinguish between components that are largely inductive or
largely resistive according to the values of inductance and resistance that it
has measured. This is illustrated in the following graph.
For example, if the inductance of your component is measured at 100µH and
it has a DC resistance of 100Ω, then the
LCR40
will tell you that you have a
resistor. If however the resistance was only 10Ω, then the
LCR40
will tell you
that you have an inductor.
Note that any inductor with a DC resistance of more than 1000Ω will be
identified as a resistor.
