Double-circuit measurement and display instrument

A double circuit measurement display instrument relates to an industrial automatic instrument, which is characterized in that: the instrument comprises a signal input end (1), a signal input end (2), an analog signal switch, an A/D converter, a CPU processor, a memory and an LED display, wherein the sequence controls of programs to be executed, the operational algorithms of various physical quantities, and the scientific operational algorithms of addition, subtraction, multiplication and division of two lines of signals are stored in the program memory, the CPU processor instructs the analog signal switch to open a corresponding analog signal passage and at the same time calls the operational algorithms and programs corresponding to the analog signal to carry out operation and processing and at last displays the operational results on the LED display, thereby realizing the aim of measuring, displaying and controlling various analog signals.
