Measuring winding DC resistances with probes did not work - contact

That is a standard four-terminal measuring technique used for low value
resistance.

I do have a 6.5-digit bench top digital multimeter.

The problem was that I didn't have four hands, and clip leads were too
flaky as well.  All such problems were solved using the 6-bar terminal
strip.
