A bit of a false lead. I took the readings after an hour of warmup. However, after about two hours, the zero reading went to less thatn 0.2 uV, which seems just fine to me. I guess i just needed to get a really good warmup time.
However, the 752 readings are varying over several uV when doing the CAL procedure. I am currently using unshielded leads so I suspect I am getting a lot of noise. Time to invest in some really good cables I guess. I was hoping to build my own cables as Bill Gold had suggested in a previous thread.
