Current Connectors
Sense Connectors
The lower (male) connectors are labeled Sense Connector . They contain only high-impedance inputs used to
sense potentials in the cell.
In addition to the pins used for cell connections, each EIS Box Cell Connector also uses four pins to read a cell
cable ID. Gamry software can compensate for the cell-cable characteristics to attain optimal system
performance in EIS (Electrochemical Impedance Spectroscopy).
The cell connections are discussed in Chapter 3. A pin-out description of the cell cable connector is found in
Appendix B.
Channel LED
A
Channel
LED is between each pair of Cell connectors.
The Channel LEDs glow amber whenever the EIS Box is actively applying voltage or current to the
electrochemical cell attached to that channel. Avoid touching the cell cable leads whenever the Channel LED is
lit, because the quality of the data being collected in your experiment may be compromised.
If you need to make changes to your cell leads, do so after powering down the EIS Box.
In a typical experimental sequence, the Channel LED is off between experiments and during any open-circuit
potential measurements. It glows amber whenever th at channel’s cell is polarized.
The Channel LED does not indicate a dangerous condition when it is lighted. The voltages
generated by the EIS Box are generally considered safe. Still, avoid touching the cell leads when the cell is
on.
