A .03%
METER CAN BE USED, ESPECIALLY WHEN THAT METER IS AVAILABLE WITH
NIST CERTS, NOW CAN'T IT????

NOPE.

Now tell us why not? Exactly what kind of standard is required to
adjust a scope's vertical response to 3% as it's specs state?

0.75% or better accuracy.(4X or better)
(and that would be "adjust to within 3%". the actual result may be
better than 3%;you just can't depend on it staying that way for any
length of time.)

Thanks Jim, I feel like I finally heard something I could put some stock
into. Just to set the record straight, would it be legitimate to "certify"
a device to 3% (DUT specs) using a .03% accurate DMM that has an NIST cert?
Really, it's just a matter of personal curiosity now.
