1. Under
Stimulation, select Ground.
2. Click any electrodes that you like to ground, for example electrodes 36, 46, and 56. Grounded
electrodes show no electrode number, only a blank button. By clicking on one of the grounded
electrodes again you can toggle back to recording mode. If you click, for example in Stimulation
mode B onto a grounded electrode, you overwrite the grounded mode with Stim. B mode. That
means, the color will turn to red and the number of the electrode appears again. If you click for
the third time, the selected electrode toggles back to recording (= default) mode.

4. Switch to the MC_Rack display.
You can see that the noise level of the grounded electrodes is reduced. The effect is quite
small because the model test probe has no defective electrodes and shows a fine low noise
level on all "electrodes".
