Operation Overview
Figure 3- 1 shows a “typical” electrochemical test system built around an EIS Box instrument. Only four cells are
shown in this figure, although up to eight cells can be connected.

A Typical Electrochemical Test System Using the EIS Box
The
system computer is a critical component of the system. It controls the EIS Box by sending it simple
commands through an ethernet or USB connection.
The most important function of these commands is to select which cell is
active (connected to the EIS Box ) . You
can think of an EIS Box as a complex switch with driving electronics. One of the eight cell cables on the EIS Box
is switched so that it connects to the instrument
’s cell cable. All of the wires (including sense leads and shields)
in the cell cable are switched.
