Appendix B -- Reference 3000 Cell Connectors
Chapter 5 describes the connections between a cell cable and an electrochemical cell. This appendix describes
the other end of the cell cable.
Multiple pins assigned to the same signal are connected together on the Reference 3000’s Potentiostat board.
If you need to connect this signal outside the Reference 3000, you need a wire connected to any one of the D
connector pins.
Table B-1
Counter/Working Connector
Pin(s) Signal Name Use
1,9 Working Connected to the working electrode (see Chapter 5).
2, 10 Working
Shield
The shield for the working electrode. Connected to Floating Ground on D
end of the cable Left open at the cell end of the cell cable.
3 No connect
4, 6,11,13 Ground The potentiostat's floating ground. Can be used to shield the cell if very low
currents need to be measured. Also used as a shield for the counter
electrode cable.
5,12 Counter Connected to the Counter Electrode
7 CBL_ID1 One of 4 cable ID bits. Used to identify the type of cell cable attached to the
unit. Pull to a logic High through a resistor. Ground to set the bit low.
8 CBL_ID2 One of 4 cable ID bits. Used to identify the type of cell cable attached to the
unit. Pull to a logic High through a resistor. Ground to set the bit low.
14 CBL_ID0 One of 4 cable ID bits. Used to identify the type of cell cable attached to the
unit. Pull to a logic High through a resistor. Ground to set the bit low.
15 CBL_ID3 One of 4 cable ID bits. Used to identify the type of cell cable attached to the
unit. Pull to a logic High through a resistor. Ground to set the bit low.
