Error in calorimetric effective efficiency measurements due to DC losses

June 13, 2010
Author(s)
Thomas P. Crowley
A phenomenon in which DC loss in a transfer standard results in incorrect calorimetric effective efficiency measurements is described. The DC loss occurs within the 4-wire leads of the transfer standard or its connector. It therefore affects calorimetric
