Description: A provisional standard method of measuring tonic skin conductance (SCL) and GSR (SCR) is advocated, using a constant-voltage method for which circuits are provided useable with Beckman, Grass, and other common polygraphs. A standard electrode methodology is also presented. The problem of units of measurement is considered in detail with an analysis of the so-called Law of Initial Values. Methods are given for correcting both tonic SC and SCRs for individual differences in their respective ranges of variation and the purpose and relative advantages of these range-correction methods are discussed.
