Thermal EMF effect on low DC current measurement

Question asked by bar28 on Mar 13, 2013
Does anyone know, how to estimate value of thermal EMF effect, when measuring
low DC current (10uA to 1mA) using Agilent 3458A? Many appication notes and specification
says, that EMF should take account on uncertainty calculation when doing voltage and resistance
measurements, but no excat information when measuring DC current. Is EMF effect on low DC current
measurement around picoamps level or what?
