<Resistance surge voltage>
Apply pulse sample resistor measure rate resistance change. Raise voltage gradually until rate resistance change exceeds 0.5%. threshold pulse voltage defined upper limit voltage hold rate resistance change within 60.5%.
<Resistance polarization>
ohmic resistor receive internally effects thermal electromotive force. minimize effects thermal electromotive force ohmic resistors through thin film technology. effect thermal electromotive power could detected measuring polarization resistance values.
