    Abstract: Subject matter herein can include identifying a biochemical test strip assembly electrically, such as using the same test circuitry as can be used to perform an electrochemical measurement, without requiring use of optical techniques. The identification can include using information about a measured susceptance of an identification feature included as a portion of the test strip assembly. The identification can be used by test circuitry to select test parameters or calibration values, or to select an appropriate test protocol for the type of test strip coupled to the test circuitry. The identification can be used by the test circuitry to validate or reject a test strip assembly, such as to inhibit use of test strips that fail meet one or more specified criteria.

    Abstract: Sensor error detection with an additional channel is disclosed herein. First and second magnetic sensing elements can be disposed at angles relative to each other. In some embodiments, the first and second magnetic sensing elements can be magnetoresistive sensing elements, such as anisotropic magnetoresistance (AMR) sensing elements. Sensor data from first and second channels, respectively, having the first and second sensing elements, can be obtained. Third channel can receive a signal from the first sensing element and a signal from the second sensing element, and sensor data from the third channel can be obtained. Expected third channel data can be determined and compared to the obtained third channel data to indicate error.
