Abstract
According to a conventional technique, when a calibrated temperature measuring probe is used for correcting the temperature absolute values of individually temperature-controllable thermal control blocks, a temperature difference of a maximum of 0.5° C. remains between the thermal control blocks. According to the present invention, the melting temperature of a temperature calibration sample housed in a reaction vessel corresponding to each of the temperature control blocks is measured as a measured melting temperature. The measured melting temperature corresponding to each of the thermal control blocks and the reference melting temperature of the temperature calibration sample are compared, and the temperature absolute value of each of the thermal control blocks is corrected based on respective difference values.
