Thermal Protector Ohmic Resistance Test

It’s executed an Ohmic Resistance Measurement just like the windings (see Ohmic Resistance Test) but with the possibility to set the Thermal Variation Coefficient, which represents the percentage variation of the Rated resistance value for each variation of the degree of the temperature. This value is used during the phase of normalization of the measured value with real temperature. In alternative it is possible to set the polynomial coefficient of the curve that describe the Ohmic Resistance if function of the Temperature.
