Tab. 11: Resistance value Ni1000

The resistance value of the nickel measuring resistor changes in relation to

the temperature. The temperature coefficient is always positive, i.e. the
resistance increases as the temperature rises. See the table of values
(DIN 43760). Within the specified tolerances, the sensors can be exchanged
without calibration.
