Comparison for Ultra-low DC Current Sources

Project Description

Supplementary comparison on this subject, EUROMET.EM-S24, was carried out from 2005 to 2009. The objective of the proposed comparison is to provide technical evidence supporting their CMCs entries of those participants who did not participate in the EURAMET.EM-S24, while other participants would have an evidence for confirmation of their improvements in this field of measurement. The comparison will be performed at the points of ± 9.5 fA, ± 95 fA, ± 0.95 pA, ± 9.5 pA, ± 95 pA. A commercial picoamperemeter, which is a Keithley 6430, will be used as travelling standard.

Progress Report 2019-09-30

All the participants performed measurements, except a new participant VNIIFTRI, Russia. The travelling standard has been sent to Russia as of the date of 27.09.2019. After VNIIFTRI measurements, the travelling standard will be measured in TÜBİTAK UME for the last time.
