WR14 / WR50-12/13 Winding Resistance Meter Instruction Manual
Showing the graph in °C
When the resistance of the winding at any specific temperature and the material is known, all the values
can be displayed as °C.
Enter the resistance value (Rcold) of the winding,
the corresponding temperature (Tref) and the
temperature coefficient of the conductor.
The approximation and the values are shown as Temperature.
Linear Approximation:
T0: Temperature at time t = zero
m: Slew rate dt/dt in °/ min
Cor: Correlation of the approximation
Exponential Approximation:
T0: Temperature at time t = zero
R∞: Temperature at time t = ∞
tau: Time constant
Cor: Correlation of the approximation
