Hi All,
We have 3 units on site for evaluation, 1 is freshly cal , 2 are not calibrated.
both display about -4uV with a low thermal EMF short installed.
We then inserted the short (34172b) to the 2 units that are not calibrated, let it sit for 1 day then we ran through the DC cal step 0 - 3.
However after cal, the 2 units are still at -4uV when short is installed.
this is giving me 0.5% error at 1mV input.
Anyone having ideas if this is normal?
Regards,
Li
