In the early stage of the experiment, there is a "turning point" in the temperature at the end of the experiment, which is critical for judging the endpoint of temperature rise. To accurately determine the trend of temperature change, i.e., when strictly following the Ruff formula for measurement, the required testing time is long. In the method of shortening the measurement time through "temperature rise trend" prediction, i.e., the "fast mode," the prediction of the temperature rise trend often becomes the key to the success or failure of the experiment. According to the different temperature control methods of the outer cylinder, it can be divided into: Isoperibolic calorimeter: The outer cylinder has no temperature control. To keep the water temperature in the outer cylinder basically consistent during the measurement process, the heat capacity of the outer cylinder is usually 5-10 times that of the calorimeter after being filled with water, i.e., it usually has a 20-40L outer cylinder filled with water. However, since the outer cylinder has no temperature control, sometimes the water from the inner cylinder also circulates into the outer cylinder, so after several measurements, the temperature of the outer cylinder rises slowly and significantly. Peripheral isothermal calorimeter: On the basis of the isoperibolic calorimeter, temperature control of the outer cylinder is added, reducing the volume and water capacity of the outer cylinder.

. Press the calibration key on the keyboard
2. Enter the weight of the standard substance
3. Press the calibration key, at which point the instrument begins to automatically drain water and enters the analysis stage. After three minutes, it automatically ignites, and after about fifteen minutes, the printer automatically prints the results, marking the end of the experiment.
Reverse calibration standard substance instrument indicators have met the standard: Press the calorific value key on the operation keyboard, enter the weight of the standard substance. Then press the calorific value key, enter the weight of the additive (0). Then press the calorific value key, and the instrument begins analysis. The instrument will automatically alarm when the analysis is complete. At this point, all calibration is finished.
