Electrochemical-based analysis test strips with electrode voltage sense connections and handheld test strips for use with them

摘要

A hand held test meter for use with an electrochemical-based assay test strip in the determination of an analyte in a body fluid sample, comprising: a housing; A strip port connector disposed at least partially within the housing and configured to receive an electrochemical-based analysis test strip; A microcontroller disposed within the housing and configured to generate a microcontroller command signal; An electrode bias drive circuit block disposed within the housing and configured to generate a bias drive signal based on a microcontroller command signal; And configured to receive the at least one sensed electrode voltage and to adjust the bias drive signal from the electrode bias drive circuit block based on the sensed electrode voltage to generate an adjusted bias drive signal, Bias drive control circuit block.
