Dummy cell is a simulation cell. It's used to check whether the potentiostat is normally working. When you receive a potentiostat, you can use it to ensure the potentiostat is well-functional. During tests if you find results are abnormal, you can also use it to check whether it's caused by the malfunctioning of potentiostat instrument (In most cases, abnormal results are due to factors in your testing system, like improper cable connection, electrodes, etc).

During experiment, the potential and current value should always obey the Ohm law: I= E / R The R is 1.1kΩ for the dummy cell. So if you apply a constant voltage (potentiostatic) or a constant current (galvanostatic), the voltage and current should be accurately applied and displayed in the software, and the obtained current or voltage value should obey the Ohm law. We usually run potentiostatic and galvanostatic test to check the potential and current output of the instrument.
