DC millivolt millivolt level table for the accurate measurement of small signals, Used in experimental testing, production testing and maintenance of the use of.

DC millivolt table is commonly used measuring instruments, the use of digital manipulation can make a more intuitive, and fast response, is an ideal measurement tool millivolt range.

This paper describes the system structure and working principle, to build a DC mV meter hardware and software system design of data acquisition and processing and display part of the process.
