Subject: Re: [Homebrew_PCBs] Re: SMD caps - no marking - why?

It doesn't seem to take 4mm test leads.
I have some meters with that kind of slot thingy, and never use them.
It's just so much more practical for me to use normal test leads.

This is also useful:

You can also use half of a set of kelvin leads, like these:

I use them often when I can't find the first type in my mess.


Both types of probes can now be bought very cheap direct from china,
no need to spend big $.

If you need to measure a lot of caps there are test fixtures, probably
a bit expensive to buy but should be fairly easy to make yourself:
