LC100 LC meter seems like a good deal

I recently bought an LC100A LC meter from eBay, like the one shown below. If you search eBay, you’ll find them on sale anywhere from $20 to $40. Yesterday, I finally got around to playing with it a little.

To power the device, you need to supply +5V. It comes with a cable that has a USB connector on one side and a power connector on the other. Obviously, it’s meant to be powered by a USB port. I used a power adapter that I purchased to charge an iPod. It worked great.

As a quick test, I measured the capacitance of ten 0.33 uF caps that I purchased for a project. I first measured the capacitance with the LC100A and then with the fancy-schmancy Keithley 2110 that I purchased about a year ago. Below are the results:

LC100 2110
1  .35 .339
2  .33 .326
3  .33 .318
4  .33 .322
5  .33 .324
6  .34 .328
7  .34 .330
8  .34 .329
9  .34 .330
10  .33 .316

Now, this wasn’t a very scientific test, but I am pleased with the results. I also measured the value of some 330 uH chokes that  I had. They all measured between 315 and 320 uH.

So, all in all, I think this is a good deal for the money. I’m looking forward to using it on some of my projects. The next step is to find a box to put this in. I’m surprised that no one seems to have found one yet.

  1. You can find them “boxed” on ebay as well Dan. By the way if you ever get display problems you probabely need to read my blog:

    Thanks for the tip, Bas!

  3. Hi Dan. I put mine in a clear top tin, just like the ones the Four State QRP group sold some time ago, see http://www.4sqrp.com/ClearTopTin.php They aren’t that difficult to find in the US, but harder elsewhere.
