摘要
Various embodiments for methods and systems that allow for detecting of a direction in which a sample is flowing towards a plurality of electrodes and detecting a fill error of an electrochemical test strip (100). This includes monitoring the working electrodes (8,9,10,12,14,15) such that it is possible to determine fill direction/location by determining which electrode breaches a predetermined threshold first. This applies to systems with a plurality of electrodes in a number of orientations. Further, for systems which have analyte measurements along with physical characteristic measurement, it is also possible to achieve the same objectives by determining when each measurement (analyte measurement versus physical characteristic measurement) happens relative to the other. For test strips which can be filled from either side, the role of any electrode can change depending on the determination of fill direction. A measurement electrode can double up as a fill detect/full sufficiency electrode if it is determined that based on fill direction this electrode is now the last electrode in the chamber.
