Sense Inputs Connector
Pin(s) Signal Name Use
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 Ohm 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 Ohm resistor in the cell end
of the cable. Custom cell cables are likely to require a similar resistor.
13 Reference
Electrode
Connected to the reference electrode in most cases (see Chapter 5). This
lead has a 261 Ohm resistor in the cell end of the cable. Custom cell cables
are likely to require a similar resistor.
