ABSTRACT:
A heat analyzer equipped to automatically perform operations necessary for protection of measured data and for restart when a problem occurs or a measurement ends and to quickly turn off all power sources by a command input manually by an operator to a system section after daily use. At least one measurement-section power source 6 which can be turned off by an associated measurement controller 5 and a system-section power source 14 which can be turned off by a system controller 11 are included. When the temperature program of every measurement controller 5 connected to the system controller 11 through data transmission paths 8a to 8c is executed, an external environment sensor 9 detects a problem, or the operator issues a command, the system controller 11 transfers information from volatile memory 10 to a nonvolatile memory 13 before commanding every measurement controller 5 to turn off the measurement-section power source 6 and providing the system-section power source 14 with a control for turning off the system-section power source.
