j. Component Test
Use Component Test to measure the characteristics of a
passive component (in or out of circuit, no power applied).
The 440 provides an AC stimulus signal to the component and
plots the voltage drop against the current measurement. The
resulting pattern provides information about passive circuit
condition.

Diagrams are displayed on the LCD that can be used to rough-
ly identify components being measured. The diagrams below
show typical signatures for the components that are indicated.
Some components may be difficult to distinguish due to simi-
larities in pattern, however, the determination of a good or bad
component can be made.
