1
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.
2
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.
3,4
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.
5,6,12,14
Reference
Shield
The shield for the reference electrode input. Driven to the same potential as
Pin 16. Left open at the cell end of the cell cable.
7,15
Work Sense
Shield
The shield for the work-sense electrode input. Driven to the same potential
as Pin 8. Left open at the end of the cell cable.
8
Work Sense
Connected to the working electrode in most cases (see Chapter 5). This lead
has a 261 Ω resistor in the cell end of the cable. Custom cell cables are likely
to require a similar resistor.
9
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.
10
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.
11
Counter
Sense
Connected to the counter electrode in ZRA-mode and stack-mode
experiments (see Chapter 5). This lead has a 261 Ω resistor in the cell end of
the cable. Custom cell cables are likely to require a similar resistor.

). This lead has a 261 Ω resistor in the cell end
of the cable. Custom cell cables are likely to require a similar resistor.
