Page 11: Chapter 1 -- Safety Considerations
The “AC Adapter” supplied with the Reference 3000 is certified under EN 60950. The AC Adapter converts the AC mains voltage to 24 volts DC, which is used to power the Reference 3000. You should always use the AC adapter (power brick) supplied with your Reference 3000 to supply DC power to the instrument. -
Page 12: Ac Mains Connection To The Power Brick
Grounding in the Reference 3000 The circuitry and the metal case of the Reference 3000 are not connected to an earth ground. If they were connected to earth ground, it would compromise the Reference 3000’s ability to make measurements in electrochemical cells that contain earth grounded conductors. -
Page 13: Operation With Earth Grounded Cells And Auxiliary Apparatus
An earth ground connection can cause problems when testing batteries, fuel cells, or capacitors. Many of these devices can source huge currents, often 10’s or 100’s of amps. If the Reference 3000 chassis is earth grounded and another location in the stack is accidentally (or intentionally) connected to earth ground, a portion of the stack is shorted through the Reference 3000’s cell cable. -

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. - Page 22 Chapter 3 -- Instrument Circuitry--Reference 3000 Schematic/Block Diagrams Figure 3-1 Reference 3000 Potentiostat Board in Potentiostat Mode Simplified Schematic/Block Diagram 3 - 2...

One channel is dedicated to measurement • of the potentiostat’s current signal, another is used to measure the cell or stack voltage, and the third is switched between a wide selection of possible signals.
- Page 26 The Aux ADC BNC input is a differential input. Some of this input’s characteristics can be changed by • either jumpers or CMOS switches. Early Reference 3000’s use jumpers to change the characteristics, while later units (shipped after the middle of 2009) will use CMOS switches under software control to change the characteristics.
- Page 27 Unlike previous Gamry Instruments Potentiostats, the Reference 3000 calibration data is stored in the instrument, not in a data file. When a Reference 3000 is moved from one computer to another, its calibration remains valid.
- Page 28 Additional circuitry that is not shown protects the Reference 3000 against ESD (electrostatic discharge) • and electrical surges. Note that the Reference 3000 is also protected against damage if an incorrect polarity power input is connected to the unit. WARNING Do not use a DC power source other than the AC adapter model provided with your Reference 3000.
- Page 29 The inputs will not be damaged by connection to voltages as large as ± 36 volts versus the Reference • 3000’s ground, regardless of the compliance voltage setting. This is true even when the Reference 3000 is not powered up. They cannot measure voltages larger than the compliance voltage.

Page 69: Chapter 8 -- Stability In Potentiostat Mode
Whenever you see sharp breaks in the current recorded on the system, you should suspect oscillation. The Reference 3000 has been tested for stability with cell capacitors between 10 pF and 0.1 F. In all but its fastest control amp speed setting, it is stable on any capacitor in this range -- as long as the impedance in the reference electrode lead does not exceed 20 kΩ. -
Page 70: Improving Potentiostat Stability
Improving Potentiostat Stability There are a number of things that you can do to improve an unstable or marginally stable Reference 3000 potentiostat/cell system. This list is not in any particular order. Any or all of these steps may help. - Page 71 Chapter 8 -- Stability in Potentiostat Mode--Improving Potentiostat Stability Provide a high frequency shunt around the cell. A small capacitor between the red and white cell • leads allows high frequency feedback to bypass the cell. See Figure 8-2. The capacitor value is generally determined by trial and error.
- Page 72 Chapter 8 -- Stability in Potentiostat Mode--Improving Potentiostat Stability Add resistance to the counter electrode lead. See Figure 8-3. This change lowers the effective • bandwidth of the control amplifier. As a rule of thumb, the resistor should be selected to give one volt of drop at the highest current expected in the test being run.
