US 7,212,925 B2 · Calibration data entry system for a test instrument

Abstract

A test device for determining the analyte concentration in body fluid. The test device has a memory in which calibration adjustments corresponding to calibration numbers are stored. The test device is adapted to receive a test sensor for collecting a sample. The test sensor contains a reagent adapted to produce a reaction indicative of the analyte concentration in the sample and the test sensor has an associated calibration number of a plurality of digits. The test device comprises a measuring unit, a single calibration input element, a user display, and a processor. The measuring unit measures the reaction of the reagent and the analyte and generates a signal indicative of the measured reaction. The single calibration input element permits a user to input the calibration number, one digit at a time, associated with the test sensor. The processor is adapted to determine the analyte concentration. The user display shows available digits to be selected by a user inputting the calibration number and displays the determined analyte concentration.
