hey Bill, any pointers on how I might use and verify this?
looks like a calibration standard (might be that type printed on it
)
and came from
Micro Components Technology
of course there isn't any reference to such a minor little device on the site
those are DB15 connectors on each end
and there are just old calibration stickers on the other side
National Cal & Stds LAB (NIST affiliate? some other country's standards lab?)
tag # date (94), due date (95), and
D.B.S./CO134
52 AAA
whatever that means
Id like to first try to "use" it
then see about getting it recalibrated
