Abstract
A study has been made of calorimetric errors resulting from the use of potential leads effectively at the midpoints of current lead segments between a calorimeter and its surrounding shield. An experimental arrangement is suggested to avoid errors due to thermal conduction along potential leads. Using a mathematical analysis, errors due to different thermal contacts between current lead and the calorimeter and shield are also considered. It is concluded that when accuracies of better than 0.1% are desired, careful consideration should be given to heater lead design.Keywords
