[Hallicrafters] Measurement of Low Resistance

[David C. Hallam]

Several months ago someone posted a link to an article in an old electronics
magazine (on this list I think) on a practical method to measure low
resistances.  I thought I saved the article, but I can't find it on my HD.
Does anyone remember this article or a similar one?

I have an old transmitter I am restoring and want to check some ground
connections to see if they are really at ground.
