Abstract
A reagent strip calibration system utilizes an electrical connection system particularly usable for making electrical connections to one-time use devices such as reagent strips. The connection employs a plurality of U-shaped contacts fabricated from a hard metal wire such as tungsten, beryllium copper or a nickel/iron alloy that is self-supporting or supported by an elastomer that also provides contact pressure between the wire and the one-time use device while providing low insertion force. Such a connection system is particularly suitable for use with a system for analyzing the chemical properties of an analyte that is placed on a reagent strip. The manner in which the chemical properties of the reagent strip are to be analyzed are defined by areas of different resistance disposed on the reagent strip and contacted by the U-shaped contacts to permit measurement of the resistance of the various areas to obtain the information needed to define the properties of the reagent strip.
