Zusammenfassung:	PURPOSE:To improve the precision of the heating control temperature of a heating device by connecting a resistor and a variable resistor in series to a thermister type sensor and adjusting the variable resistor to use the variable resistor for the heating device. CONSTITUTION:The variable resistor 12 and the resistor 13 are connected in series to thermister type sensor 5 as one unit. The unit sensor 5 is set up in a thermostatic oil oven and a fixed voltage of +10V is applied between terminals 15a and 15c. The variable resistor 12 is adjusted so that the voltage corresponding to that of the heating device is outputted from a terminal 15b. After completing the adjustment, the variable resistor 12 is fixed and used for the heating device. Consequently, an error of the unit at a temperature around 150 deg.C can be made almost zero.
