Converting Resistance Measurements
The WRM can convert the resistance reading of the device under test at its present
temperature to the equivalent resistance value at a different temperature. The conversion is
accomplished by the following formula:
Rs = Rm (Ts + Tk) / (Tm + Tk)
Where:
Rs is the resistance at desired temperature
Rm is the measured resistance
Ts is the desired reference temperature
Tm is the temperature at which the resistance was measured
Tk is the constant used for the winding material
Tk = 234.5 for copper
Tk = 240.0 for aluminum
