摘要： An analyte meter having a test strip port is configured to detect an inserted test strip using an unpowered grounded op amp while the analyte meter is in sleep mode. After a test strip is inserted and the meter is activated, the op amp is powered and provides the sample current for measuring an analyte concentration in the sample.

摘要： A hand-held test meter includes a strip port connector to receive a test strip. A signal-measurement circuit applies a periodic voltage signal across a sample applied to the strip and detects a resulting current signal. The circuit provides data of the current signal at a digitizing frequency and a selected phase with respect to the voltage signal. A processor records one or more value(s) of the data and then alters the selected phase. Value(s) are thus recorded at each of a plurality of phases. The processor determines a phase difference of the current signal with respect to the voltage signal using the respective sets of value(s). A method for employing a test meter and a test strip is also disclosed, and includes measuring a respective plurality of points for each of a plurality of different measurement phases and determining a phase difference of a fluid sample therefrom.

摘要： A portable analytical test meter is designed for use with an associated analytical test strip. A test-strip-receiving module receives the analytical test strip and is electrically connected to a dummy load calibration circuit block. That block is configured to provide a dummy magnitude correction and a dummy phase correction; and a memory block is configured to store the dummy magnitude correction and the dummy phase correction. A method for calibrating a portable analytical test meter for use with an analytical test strip includes determining a dummy magnitude correction and a dummy phase correction of the portable analytical test meter using a dummy load calibration circuit block of the portable analytical test meter. The dummy magnitude correction and the dummy phase correction are stored in a memory block of the portable analytical test meter. Using the stored dummy magnitude correction and stored dummy phase correction, an analyte is determined.

摘要： An analyte meter having a test strip port is configured to transmit an electric signal through a received test strip with a sample. A pair of electrodes apply the electric signal and receive an electrical response from the test strip. A processing unit analyzes the electrical response and uses the response to determine an analyte level of the sample.
