Section 3. Installation
C3 to CV-27 Voltammograph
A single cable connects the C3 to the CV-27. Stirring and purging are manually controlled.
The connection of the cell lead cable is shown in Figure 5. The cell lead cable has a
stainless steel LEMO connector at each end. One end is inserted into the CELL socket on
the back of the C3. The other end is inserted into the CELL socket on the back of the CV-27.
The ends are identical; therefore, it does not matter which end is connected to the CV-27 or
the C3.

C3 to Non-BAS Instruments
The C3 should work, at least in the manual mode, with virtually any instrument. Cables
must be custom made by the user. The CELL cable is modified by cutting off one of the
LEMO connectors and attaching the appropriate connector for the particular instrument. The
color code for internal wires is red (auxiliary electrode lead), white (reference electrode
lead), black (working electrode lead), and bare (ground). Alternatively, if the instrument has
a cell lead with alligator clips, disconnect the cell leads that are in the front panel of the C3
and connect the alligator clips directly to the electrodes. If automatic control is desired, see
Section 4 for information on the pin outs of the REMOTE connector for construction of the
proper cable.
Use with Low Current Module and Impedance Module
The C3 is designed to accommodate Low Current Module and Impedance Module
accessories. Remove the cell lead box by loosening the two thumb screws (see Figure 2)
from the back panel and sliding the cell lead box out. Slide in the appropriate module and
tighten the thumb screws. It is important that the thumb screws be tight to ensure proper
grounding of the case. Connection and operation of the Low Current Module and Impedance
Module are described in their respective Instruction Manuals.
