Appendix B - Component Identification
It is important to appreciate that the Atlas LCR can only decide on the identity
of the component under test using results of the electrical tests that it performs
on the component.
The Atlas LCR determines the type of component under test according to the
following criteria:
Inductor and Resistor Detection
The Atlas LCR 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 Atlas LCR will tell you that you have
a resistor. If however the resistance was only 10Ω, then the Atlas LCR 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.
