Abstract
A control apparatus can monitor the internal temperature and ambient temperature of the control apparatus and save the appropriate information in the memory media of the control apparatus if the difference between the internal and external temperature exceeds the required temperature range. Even if the temperature gradient is too steep, the required information can be saved in the memory media of the control apparatus.
