The dummy test cell provided with MedPstat is primarily used for calibrating instruments and checking the current ranges. So, we provide a 1K resistor, which allows for easy testing of the instruments. If you encounter any issues or have doubts about the readings, simply connect the instrument to the dummy cell and run one Linear Sweep Voltammetry (LSV) from -1 to 1 V. In the result plot window, observe that the current range is displayed from -1 mA to 1 mA.
