[ What is claimed is:] [1.]1. A method for compensating for offset, gain, and linearity errors in a measured signal, s, sent from an probe accessory to an electronic measurement instrument via a conductive pathway, said probe accessory serving the function of monitoring one or more of electrical parameter such as voltage, current, impedance, or frequency, said measured signal communicating an uncorrected indication of the monitored electrical parameter's values, the method producing an error corrected signal, S, having reduced offset, gain, and linearity errors over a predetermined range of calibrated values, the method comprising the steps of:calibrating the probe accessory and conductive pathway with respect to a particular one of the electrical parameters to find four or more coefficients for a correction function having the form: S=Cs.sup.2 +Bs+A+b.vertline.s.vertline..sup.x, where 0
