I don't even like the Geico Gecko. I found the Dell Dude less
irritating.

Anyway, alligator clips do change by several times 0.01 ohm when they
move
slightly, so what happens when you clip them together, zero it, then
separate them and clip them to the DUT? Maybe if it was a Fluke it
would
come with better clips, but ordinary alligator clips don't seem
adaquate.


I don't use alligator clips with the ESR meter. I have some of the
old fashion H. H. Smith test probes with very sharp tips. (Think steel
78 phono needles) that are stuck into the tinned lead, (or solder on a
PC board.) then I zero the meter. OTOH I have a set of the insulation
piercing alligator clips made for telco work. One jaw has a bunch of
VERY sharp pins that go though insulation or corrosion to make a low
resistance connection. I don't know where you would buy them. They may
be old Western Union equipment.

Agreed. Croc' clips and normal meter probes are pretty useless for making R
measurements. Even 4 wire Kelvin types I've tried, were pathetic down in
the 10m ohm area. 'Scope probe tips another example, too clunky be much use
with surface mount.
Make my probes from steel sewing needles, epoxied into pen bodies. Ideal for
cutting through oxide layers, or probing tiny SM items. Sufficient strength
to give a little and not snap off like the Tungsten carbide types.
