The sense (gray) and working (green) leads are connected to the working and sense
terminals, while the reference (white) and counter (red) leads are connected to the
reference and counter terminals. The picture blow demonstrates the connection to the
dummy cell:
As this is an AC Dummy Cell, it is designed to provide a means of evaluating the EIS
performance of the system. A Potentiostatic EIS frequency scan from 100 KHz to 100
mHz at an ac amplitude of 10mV (10 points/decade sampling rate) should provide a Bode
Z plot and Nyquist Plot as follows:
The Bode Z plot (right plot above) should be horizontal at 10ohm at higher frequencies,
and horizontal at 110ohm (10 +100) at lower frequencies. The Nyquist semicircle should
