An accurate, automated 10-V measuring system

A microcomputer-based system that measures DC voltages accurately to 10 V is described. It consists of a self-checking voltage divider with a terminal linearity of +or-0.015 p.p.m. (1 sigma ), a 26-channel scanner, a stable 10-V source and at least one known voltage reference. It has proven to be particularly useful in the automatic calibration of solid-state voltage standards and voltage dividers. >
