I agree with that. My battery seemed to float at 17.0V last night, but I
turned it all off before going to bed - I wan
Hi Steve,
I would suggest two things. First, place the 8050A on it's most sensitive
DC range and see if it indicates any voltage across the resistor. Assuming
there is nothing present, then I would suspect AC pickup on the meter leads
and a path to ground that is a different impedance from o

Any ideas as to what's going on? How can I improve my measurement
procedure to get repeatable results? Do I really need better climate
I'm restoring my old HP 410B VTVM, and I'm interested in seeing how much the
resistors have drifted since it was built, particularly the precision resistors
in the input voltage divider. I don't have volts-nuts caliber equipment (well,
there is a busted HP 3456A on the shelf waiting to be repair
They are not selected, think of that whole assembly as the "pre supply",
the close regulation and the standard are later.
I suspect noise would be had, but exact voltages come later.
I ordered 100 Fairchild 1N5248B (Mouser 512-1N5248B) for $3.70
Not exactly critical, but this is a fun hobby, so
