When is it necessary to recalibrate the capacity

1. Due to the varying temperature values (relative temperature values) measured by each temperature probe, their linearity is also differentConsistent, therefore, when replacing the temperature probe, the thermal capacity of the calorimeter needs to be recalibrated.
When calibrating heat capacity and measuring heat generation, if the room temperature differs by more than 5 ℃, the heat capacity should be recalibrated (although platinum resistors have good linearity within a certain temperature range, they do not need to be calibrated with average division values when working within the specified temperature range, otherwise it will cause significant errors that cannot be ignored).
