发明名称 CONTROLLED SLEW RATE TRANSITION FOR ELECTROCHEMICAL ANALYSIS
摘要 Measurement systems and methods are disclosed for minimizing the effects created by a meter's output amplifier during electrochemical measurements. In the systems and methods, transition of an excitation potential applied between electrodes of a test strip is controlled so that it is at a sufficiently slow rate below a slew rate capability of the system (but still fast enough to minimally impact overall test time) to reduce variability in the test results. The methods and systems therefore use a transition having a ramp-shaped waveform, a sinusoidal-shaped waveform or an exponential-shaped waveform. Additionally, the excitation potential can be purposefully controlled by a processor, memory driven digital-to-analog converter or external circuitry at a rate sufficiently slow to make variations in the analog electronics slew rate insignificant for all sample types and test conditions.
