How was the general calibration performed for the CS650 and the CS655?

Period average and electrical conductivity readings were taken with several sensors in solutions of varying permittivity and varying electrical conductivity at constant temperature. Coefficients were determined for a best fit of the data. The equation is of the form

Ka(σ,τ) = C032 + C122 + C2*σ*τ2 + C32 + C43*τ + C52*τ + C6*σ*τ + C7*τ + C83 + C92 + C10*σ + C11

where Ka is apparent dielectric permittivity, σ is bulk electrical conductivity (dS/m), τ is period average (μS), and C1 to C11 are constants.
