Abstract
Official abstract text for this publication.
A voltage measurement device, includes: a multiplexer that includes a plurality of input terminals at which voltage signals are inputted; a control circuit that performs voltage measurement by acquiring the voltage signal at a selected input terminal from the multiplexer; and a decision circuit that makes a decision as to whether or not an abnormality has occurred, based upon voltage values measured by the control circuit, wherein: the plurality of input terminals include input terminals at which voltage signals from a plurality of subjects of measurement are inputted, and an input terminal at which a potential for diagnosis is inputted; the control circuit, when performing voltage measurement for the plurality of subjects of measurement, measures voltages at the input terminals at which the voltage signals from the plurality of subjects of measurement are inputted, and a voltage at the input terminal at which the potential for diagnosis is inputted.
First claim
Opening claim text (preview).
What is claimed is: 1. A voltage measurement device, comprising: a multiplexer that includes a plurality of input terminals at which voltage signals are inputted, an input changeover terminal at which a changeover signal for changing over the plurality of input terminals is inputted, and an output terminal; a control circuit that performs voltage measurement by inputting the changeover signal to the input changeover terminal of the multiplexer and thus causing the multiplexer to…
