1. A diagnostic meter comprising:
- a connector comprising;
a channel having a proximal end and a distal end for receiving a test strip;
a first plurality of connector contacts and a second plurality of connector contacts disposed in the channel, the first plurality of connector contacts and the second plurality of connector contacts being positioned in the channel to contact distinct portions of a contact region of the test strip received in the channel; and
a microprocessor operable with a decoder for decoding a resistance of the contact region of the test strip as information.

Abstract
An auto-calibration system for diagnostic test strips is described for presenting data individually carried on each test strip readable by a diagnostic meter. The test strip meter may provide a predetermined varying resistance on one strip or a plurality of varying resistances from strip lot to strip lot.

8. A system for measuring a body fluid constituent comprising:
-
a test strip comprising; at least one electrically insulating layer; a conductive pattern formed on the at least one insulating layer including at least one electrode disposed on the at least one insulating layer at a proximal region of the strip, electrical strip contacts disposed on at least one insulating layer at a distal conductive region of the test strip, and conductive traces electrically connecting the electrodes to at least some of the electrical strip contacts; a reagent layer contacting at least a portion of at least one electrode; and a machine-readable pattern readable to identify data particular to the test strip, the machine-readable pattern comprising; (a) at least one of the electrical strip contacts; and (b) at least one discrete portion of electrical insulating material disposed over an entire surface of at least one of the electrical strip contacts; and a diagnostic meter comprising; a connector comprising a channel having a proximal end and a distal end configured to receive the test strip;
a first plurality of connector contacts and a second plurality of connector contacts disposed in the channel, the first plurality of connector contacts and the second plurality of connector contacts being positioned in the channel to contact the electrical strip contacts located in distinct portions of the contact region of the test strip, and a microprocessor operable with a decoder for decoding a resistance of the electrical strip contacts as information. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method of making a plurality of test strips, the method comprising:
-
forming a plurality of test strip structures on one sheet, each of said test strip structures including; (a) a sample chamber; (b) an electrically insulating layer; (c) a conductive pattern comprising including a plurality of electrodes formed on said sheet, and a plurality of electrical strip contacts formed on said sheet, a portion of which are electrically connected to said plurality of electrodes; (d) a set of electrical strip contacts individually electrically isolated to form a discrete set of contacting pads formed on said sheet and electrically isolated from said plurality of electrodes at least one of said contacts having a predetermined electrical property of a first value; (e) at least one discrete portion of a material having a predetermined electrical property different than said first value and disposed over at least one of the contacting pads to at least partially form a distinct pattern readable to identify data particular to the test strip; and separating said test strip structures into said plurality of test strips. - View Dependent Claims (19, 20)
