  • Voltage offset correction in high-throughput electrophysiological measurement system
    Patent number: 9080999
    Abstract: A computer-implemented method for controlling command voltages applied to electrodes during an electrophysiology measurement procedure using a high-throughput measurement system is provided. An initial command voltage is applied to the electrodes to obtain baseline currents respectively associated with the electrodes. A common offset voltage is determined based on the baseline currents, and an adjusted command voltage is determined based on the initial command voltage and the common offset voltage. The adjusted command voltage is applied to at least one of the electrodes to obtain an adjusted current measured by the electrode. A local offset voltage for the electrode is determined based on the adjusted current measured by the electrode. A subsequent command voltage applied to the electrode incorporates the common offset voltage and the local offset voltage.
