Classification: CPC G | IPC G

Claim 13:
14. A calculation method comprising:
acquiring, by a processor, based on a change in a temperature of a temperature controlled member with respect to a change in a temperature of a thermostatic tank measured for a plurality of temperatures of a temperature controlling member, a first approximation expression representing a relationship between the outside temperature and the temperature of the temperature controlled member at each of the plurality of temperatures of the temperature controlling member, the temperature controlled member and the temperature controlling member being disposed in the thermostatic tank, the temperature of the thermostatic tank being a temperature of a volume within the thermostatic tank excluding the temperature of the temperature controlled member and the temperature of the temperature controlling member;
acquiring, by the processor, based on the first approximation expression, a second approximation expression representing a change in one or more coefficients with respect to each of the plurality of temperatures of the temperature controlling member;
receiving, by the processor, input of a first set temperature of the temperature controlled member and a second set temperature of the temperature controlling member;
substituting, by the processor, the second set temperature into the second approximation expression to generate a third approximation expression representing a relationship between the temperature of the thermostatic tank and the temperature of the temperature controlled member; and
substituting, by the processor, the first set temperature into the third approximation expression to calculate a thermostatic tank temperature to be set.
