Calorimeter Response
The response of a calorimeter to a single pulse input as displayed by a chart recorder appears as in Figure 4.
The output voltage from a chart recorder can be converted to wattage at any time by:
W=V/S, W
i
=V
i
/S
V=Chart recorder voltage level in mV
S=Calorimeter sensitivity in mV/W
The total energy (E) in the pulse can be found by integrating the instantaneous wattage over time:

The following methods may be used to compute the total integrated energy:
