This is done by cooling the heating medium from the heater to be measured, supplying it to the calorimeter, heating it, cooling it again and circulating it to the heater to be measured, and then changing the temperature of the heating medium of the heater to be measured and the heat of the calorimeter. This is like matching the temperature of the medium and measuring the ability of the heater to be measured from the measured value of the calorimeter.

The problem was that the operation caused a disturbance in the other control system, causing mutual interference and unstable control. Further, even if the temperature of the heating medium in the heater to be measured rises or falls, the temperature of the heating medium in the calorimeter does not immediately match, making measurement by the calorific ratio method difficult.
