Page 4: Safety Instructions And Symbols
VersaSTAT MC Hardware Manual Safety Instructions and Symbols This manual contains up to three levels of safety instructions that must be observed in order to avoid personal injury and/or damage to equipment or other property. These are: DANGER Indicates a hazard that could result in death or serious bodily harm if the safety instruction is not observed. -
Page 5: Introduction
VersaSTAT MC Hardware Manual 1. INTRODUCTION The VersaSTAT MC (Figure 1), teamed with the VersaStudio software package, comprises a simple, flexible, and extremely powerful system for performing a wide range of electrochemical techniques. The VersaSTAT MC is a potentiostat/galvanostat with up to four (4) channels in a single chassis. -
Page 6: Potentiostatic Mode
1.2.1. Potentiostatic mode In this mode, the VersaSTAT MC controls the potential at the working-sense electrode with respect to the reference electrode (see Figure 2). The counter electrode is driven to the potential required (consistent with the + 12 V compliance of the control amplifier) to establish the desired working potential. -

Page 8: Inspecting Your New Instrument
1.5. Inspecting Your New Instrument As soon as you receive your new VersaSTAT MC, inspect it for shipping damage. If any damage is noted, immediately notify Princeton Applied Research and file a claim with the carrier. - Page 9 VersaSTAT MC Hardware Manual Chapter 3 shows how to set up the hardware. It describes the functions of the connections and indicator lights, and shows how to connect the VersaSTAT MC to the host computer and test cell. Chapter 4 gives the physical and electrical specifications of the VersaSTAT MC including the AUXILIARY INTERFACE connector pinouts.

2.2.2. Radio Frequency Interference In a typical application, it is unlikely that the VersaSTAT MC will act as a source of noticeable RF interference. However, when operated near particularly sensitive equipment, interference from the VersaSTAT MC could be a problem. -
Page 13: Transient Sensitivity
VersaSTAT MC Hardware Manual In the case of a signal lead, it is essential that the capacitor’s value be such as to attenuate the interference frequencies without unduly attenuating critical frequency components of the signal itself. NOTE: Keep the filter capacitor leads short! Long leads establish sizable ground loops and could additionally act as radiating antennae. - Page 14 VersaSTAT MC Hardware Manual Static discharge problems can sometimes be avoided by judiciously selecting the floor covering in the work area. The simplest approach to the problem is to discharge your body by touching a grounded metal object just before touching the instrument, particularly when making connections to the cell.

Page 15: Installation
3.1. Enabling the USB port on your PC Some PC manufacturers ship their PCs with the USB port disabled. Check for this before trying to use the VersaSTAT MC. If the port is disabled, follow the manufacturer’s instructions for enabling it. - Page 16 Attach the supplied USB cable to this connector and to the USB connector on the PC. You can connect to and disconnect from the PC without shutting down or restarting Windows or VersaStudio. FIGURE 5. VersaSTAT MC Rear Panel 3.2.1.3.

3.3. Connecting to the PC and Cell This section gives instructions on connecting the VersaSTAT MC to the host PC and to electrochemical cell and other equipment. WARNING: For operator and equipment safety, power to all instruments should be off when connecting or disconnecting cables. - Page 19 VersaSTAT MC and causing damage to the instrument. 4. The opposite end of cell cable for the VersaSTAT MC is color-coded at the tip as follows: Green – Working (WE) electrode lead. This lead connects to the electrode of interest at which the desired reactions will occur.
- Page 20 VersaSTAT MC Hardware Manual Figure 8. Two-Electrode Connection b) General aqueous electrochemistry, corrosion experiments, and most EIS experiments are connected using a three-terminal connection (Figure 9). The voltage at the working-sense is controlled relative to a stable reference electrode positioned in close proximity to the working electrode.
