How an LCR meter works.



Part 2:

Excellent video as usual Dave :-+

Just a small note, on the graph of jX vs. R. The vector is indicated as Xs (at least seems so on the graph), this vector should be the DUT impedance or Rs + jXs and when projected to the jX axis (Vert) is Xs and when projected to R axis (Horz) is Rs.

Best,

HighVoltage:
Nice video,

The Philips / Fluke LCR meters came a a few good charts and they showed exactly what you explained.

Yep, correct.

Since it was in your video, and would help me learn this subject better.  Where did your open source capacitor substitution box come from??
