The figure shows us we are going to measure the voltage across the device. Therefore<br />
the next graph, Fig.13.18, will give us detailed information regarding the measuring<br />

The level is low enough not to worry us and we proceed with our post process as before.<br />
Instead of the CV button CI should be selected.<br />

13.6 IMPEDANCE: SINUSOIDAL OR MLS<br />
Up to now we have nearly only used Sinusoidal to perform Impedance Measurements.<br />
When MLS has been used, it was to point out problems. We also stated Sinusoidal is the<br />
preferred choice. Inexperienced user might ask why the MLS Menu has impedance<br />
measuring capability at all. In fact MLS yields to accurate Impedance Measurements.<br />
It is, however, less prone to forgive errors and/or measuring set-up problems of any<br />
