menus which control the data logging function of
the calorimeter.

summary of important instrument parameters. The
monitor is used to detail the course of a test or to
observe the heating/cooling performance of the
calorimeter.

program information and settings such as:
Processes and their associated PIDs (proportional
(P), the integral (I), and the derivative (D) controls),
memory, mass storage, network.
