Reference 3000 Schematic/Block Diagrams

If you are not familiar with electronic schematics or potentiostats, you probably want to skip this chapter. This
information is for expert use only and is not required for routine use of the Reference 3000.
The following figures are partly schematic diagrams and partly block diagrams. They are intended to show the
basic principles of the Reference 3000 circuitry without the confusion of the full circuitry details. The
complexity of the Reference 3000 can be quite daunting: the Reference 3000 circuit boards contain more than
3000 components connected by almost 2500 circuit nets!
The schematic/block diagram figures show:
The potentiostat board and heat sink board in a potentiostatic control mode,

The control board circuits for signal generation,

The control board circuits for signal conditioning and A/D conversion,

The Auxiliary ADC channel input switching,

The microprocessors in the Reference 3000,

DC-DC power conversion,

The optional Multi Channel (MCE) circuitry.
