The temperature coefficient must be specified as follows: The current transformer may only be operated if it is –4 –1 connected to the RESISTRON-Temperaturregler TCR  10 10 K correctly (see section 9, "Startup and operation"). The e.g. Alloy-20: TCR = 1100 ppm/K relevant safety instructions contained in section 8.3, NOREX: TCR = 3500 ppm/K "Power supply", must be obeyed.
