Abstract

An apparatus, based on the analog intergrator principle, is designed to effect a 1-nF-108-Ω transfer with reversed dc, by permitting a digital interval timer to measure the product RC, repeatedly if necessary. Both systematic and random errors have been significantly reduced, and correction to data is not required. The apparatus is simple to construct and operate, and its transfer standard error is estimated to be ±0.23 ppm.
