It is shown that there is a second properly normalized KNO scaling function, nPn( n n) = φ{symbol}(z), which has certain advantages in the analysis of KNO scaling. First, the nPn are not influenced by the statistical and systematic uncertainties of n hence φ{symbol}(z) provides more selective power than the original KNO scaling function nPn( n n) = Ψ(z). Second, the new scaling function generates scale parameter σ = 1 since it depends only on the combination of z and the scale parameter of Ψ(z). An analysis of φ{symbol}(z) is given usinge e+e- annihilation data for charged particle multiplicity distributions.
