    摘要： An analyte test sensor for use in measuring the concentration of a particular analyte in a test sample includes a non-conductive substrate, a reference electrode deposited on the substrate, a working electrode deposited on the substrate and a compensation electrode deposited on the substrate. The compensation electrode is provided with a resistive ladder and is designed to correct for test result inaccuracies which are the result of variances in the manufacturing of the test sensor. Specifically, in one embodiment, the compensation electrode corrects for test result inaccuracies in an analog manner by shunting a portion of the working current away from working electrode. In another embodiment, the compensation electrode corrects for test result inaccuracies in a digital manner by providing a calibration code which is proportional its resistance value. A batch of analyte test sensors are preferably manufactured in the following manner. An initial batch of the test sensors is constructed. Then, a limited sampling of the sensors is tested for accuracy using a control sample. Based on the test results, the resistance value of the compensation electrode for each remaining sensor in the batch is adjusted accordingly.

    摘要翻译： 用于测量测试样品中特定分析物的浓度的分析物测试传感器包括非导电衬底，沉积在衬底上的参考电极，沉积在衬底上的工作电极和沉积在衬底上的补偿电极。 补偿电极设有电阻梯，用于校正测试结果不准确，这是测试传感器制造方差的结果。 具体地说，在一个实施例中，补偿电极通过将工作电流的一部分分流离开工作电极来以模拟方式校正测试结果不准确。 在另一个实施例中，补偿电极通过提供与其电阻值成比例的校准代码以数字方式校正测试结果不准确。 一批分析物测试传感器优选以如下方式制造。 构建初始批次的测试传感器。 然后，使用对照样品测量传感器的有限采样精度。 根据测试结果，相应地调整批次中每个剩余传感器的补偿电极的电阻值。
