Error in calorimetric effective efficiency measurements due to DC losses



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 measurements, but not direct comparison transfer measurements. Symptoms of the error and a procedure for determining its presence are described.
