Development on Miniature Intelligent Differential Thermal Analysis Instrument

A recent DTA instrument was introduced in this paper. The instrument is a distributed multiembeded processor and PC system. The PC communicates with the processors via RS 232. The PC is based on Windows 95 and VB4.0. Their work is to control the operation of the processors and to obtain the temperature and DTA data from the processors to plot data curvers on CRT, and to do variety of processing and calculation.
