How to check if the instrument works normally by dummy cell?

2024-09-19

Dummy cell is a simulation cell. It’s used to check whether the potentiostat is normal. When you receive a potentiostat, you can use it to ensure the potentiostat is well-functional. During tests if you find data abnormal or something wrong, you can also use it to check whether it’s caused by your testing system, or by the malfunctioning of the instrument.

1. Firstly, please connect the potentiostat with dummy cell by the electrode cable, and power on the instrument. If there is a white Sense(SEN) cable, you should always connect it with the green WE together. Cable connection is as follows:

2. Open the software, click “Setup” - “Restore Defaults”. Select “Potentiostatic (i-t)” in the “Experiments”. Pay attention to the OCP, and it’s should be 0. Apply 1.1V vs. RE, choose a location to save the data file by “Browse”, then click “OK”. After it runs, please check the displayed potential /current value. If it’s 1.1V and 1mA respectively, it means the test goes normally, indicating the instrument’s potential output is accurate and normal.

3. Similarly, run “Galvanostatic (E-t)”. The OCP should also be 0. Apply 1mA. Please check the displayed current and potential. If it’s 1mA and 1.1V, it means the test runs normally, and the current output is accurate and normal.

4. Run EIS to click Experiments - Impedance - Potentiostatic EIS (Nyquist, Bode). Keep the parameters setting as default and click OK to run EIS. If the instrument is well-functioning, the result should be as follows, presenting a standard semicircle.
