... Changing the Temperature Gradient through Use of External Temperature Sensor (Thermistor) The SCI7661C/M has a temperature gradient selector circuit in its regulator. It selects any one of the three gradients: –0. –0. and –0. necessary that the temperature gradient can be changed to any other value by connecting a thermistor in series to the ...
