error that is mentioned.
There is also a 6 nA (typical) leakage mentioned. During the hold time (
about 1 msec) of the output 1 ufd cap this comes to 6 uV.

Does anyone know the basic specs for a Data Precision 3600 - resolution,
accuracy?
Thanks!

If you don't read the newspaper you
purchased three 3457As on Ebay. They are
always on and I have had no problems with them. They are my current favorite
DMMs. All three indicate within a few ppm at +10.0 volts (I have not
adjusted / calibrated them).
I think HP got a lot right with the 3457A. Wish I could afford a 3458A!

easy! The lm301 is protected
against shorts to ground.
Thanks to all who added to this thread.

I've come to realize that protecting freedom
protection to the
op-amp and may be a factor in the op-amp stability.
Other than the above, can anyone see why this would be a bad idea?
Thanks,

Hello Bob,
whats the matter with you. Infected by precision virus like me?
You wanted to have a standard with about 10ppm and now you blame a 3-4ppm
drift.
:-) - afraid so Andreas!
The LM199A is hermetically sealed.

I just dropped off the Volt-Nuts TS at my shipper, headed to the fourth
volunteer for this project. I will report his measurements as they become
available.
Some drift data provided by the fourth volunteer is now available here:
