1. A method of manufacturing a plurality of analyte sensors, the method comprising:
- providing a substrate having a plurality of channels in a surface of the substrate;
locating at least one needle adjacent to the surface of the substrate and dispensing a reagent from the needle onto the surface;
contacting the surface with at least one squeegee; and
causing relative movement between the substrate and the needle between the substrate and the squeegee, wherein the needle and the squeegee cooperate to substantially fill the plurality of channels with reagent and leave a remainder portion of the surface generally free of reagent.

Abstract
An analyte measurement system is provided having sensors with embossed test chamber channels. In one embodiment, the sensors are elongate test strips for in vitro testing, each test strip having a substrate, at least one electrode, an embossed channel in the electrode, and lidding tape covering at least a portion of the embossed channel. Methods of manufacture are also disclosed for filling the sensor channels with reagent, and for trimming the ends of the sensors to eliminate the need for a calibration code during use of the sensors with a meter.

9. A method of manufacturing a plurality of analyte sensor having similar operating characteristics, the method comprising:
-
forming a plurality of substantially functional analyte sensors, each sensor having a channel extending to an edge of the sensor;
testing at least one of the sensors to determine a calibration parameter of the sensor;
based on the calibration parameter of the tested sensor, trimming a predetermined amount from the edges of the non-tested sensors, thereby shorting the channels of the sensors and changing a calibration parameter of the sensors. - View Dependent Claims (10, 11, 12)
