9. EXAMPLES

This chapter covers basic measurement procedures as well as basic L, C, and

R measurement theory. It also offers various measurement hints. After the

descriptions of basic measurement procedures, practical measurement

examples are shown using LCR-6000 Series.

9.1 Basic Measurement Procedure

The following flow chart shows the basic procedures

used to measure the impedance of capacitors, inductors,

resistors, and other components. Follow the procedures

to perform impedance measurements while referring to

the items noted to the right side of each step.
