If it's not after 5 on Friday, then it may be lack of Tecate.

Wonder if Tecate is causing the shakes

Are you isolating your DC and AC grounds?

Especially if you are using a high
impedance digital meter.
Or if they are connected via a wire
carrying high current, 0.1 volt may not
mean much. If you have 10 amps flowing
through a wire with 0.01 ohms resistance,
there’s your 0.1 volt.
If that second piece of metal is grounded
to your common ground point with a wire
that should not be carrying any current,
then I might worry about the 0.1 volt. You
might have a ground loop.
Are you seeing a DC or AC voltage?

That's what i was going to say. If it's a
cheap meter, don't worry about it. Bond
everything and you should be fine.

Depends on the meter. Does the meter read
0.0 when the leads are shorted together?
Some meters have some random fluctuations
in the least significant digit all the time.

*Subject:* [AFMUG] Another ground question
I'm working on a new DC enclosure (steel
19" rackmount cabinet). When using a DC
volt meter, and putting the 'red' lead on
a common ground point (my ground bus, a
metal rack rail, etc), and the 'black'
lead on something metal, I'm seeing ~0.1V.
I'm assuming this is bad. On the bench
currently, I have the AC ground connected
to my PSU. I have all other devices
(switch, surge suppressors, rack rails,
etc) tied to a common ground that isn't
yet connected to earth. My PSU and power
distribution is on a metal DIN rail which
in turn is mounted to the metal rack rails.
Should I be concerned with this? As much
as I try (or not), I still have trouble
wrapping my head around ground/ground
potential/etc.
