    1.2.1. Potentiostatic Mode In this mode, the VersaSTAT 3F 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 +12V compliance of the control amplifier) to establish the desired working...

    Figure 2. Potentiostat-Mode Block Diagram 1.2.2. Galvanostatic Mode In galvanostatic operation, the VersaSTAT 3F controls the current between the counter and working electrodes at the specified fraction of the selected current range (up to the maximum of the current range; see Figure 2). The counter electrode is driven to the potential required (consistent with the +12V compliance of the control amplifier) to establish the desired cell current.

    The software is designed specifically to work with Windows 8 and Windows 10. 1.4. Inspecting the New Instrument As soon as the new VersaSTAT 3F has been received, inspect it for shipping damage. If any damage is noted, immediately notify Princeton Applied Research, and file a claim with the carrier.

  • Page 10: About This 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 3F to the host computer and test cell. Chapter 4 gives the physical and electrical specifications of the VersaSTAT 3F including the AUXILIARY INTERFACE connector pinouts.

  • Page 11: Safety And Component Placement

    2.1. Safety Considerations 2.1.1. Line Voltage Settings and Fuses The VersaSTAT 3F has a Corcom™ Power Entry Module on the left side of the rear panel. The Corcom module (pictured below) contains the power connector and two-line fuses. The VersaSTAT 3F automatically detects the correct line voltage and frequency, so there are no line voltage changes required in the Corcom.

    NOTE supply a suitable cell and electrodes. 2.2.1. Ventilation VersaSTAT 3F specifications apply at the nominal line voltage + and at a temperature of 25 F) unless otherwise noted. Ambient temperature must not exceed 50 C (122 F). See Section 4.3 for more detailed environmental specifications.

  • Page 13: Radio Frequency Interference

    2.2.2. Radio Frequency Interference In a typical application, it is unlikely that the VersaSTAT 3F will act as a source of noticeable RF interference. However, when operated near particularly sensitive equipment, interference from the VersaSTAT 3F could be a problem.

  • Page 14: Transient Sensitivity

    224183_0C / 082021 VersaSTAT 3F Hardware Manual 2.2.3. Transient Sensitivity Princeton Applied Research instruments are designed and constructed to ensure normal operation in the presence of moderate transient levels. Although these provisions are sufficient for operation in most places where the equipment is used, it is certainly possible for transient levels in particular environments to be so severe that they make reliable operation uncertain.

    3.1. Enabling the USB Port on the PC Some PC manufacturers ship their PCs with the USB port disabled. Check for this before trying to use the VersaSTAT 3F. If the port is disabled, follow the manufacturer’s instructions for enabling 3.2. Connectors and Indicators 3.2.1.

  • Page 16: Auxiliary Interface

    POWER: This indicator lights when the VersaSTAT 3F is powered on. 3.3. Connecting to the PC and Cell This section gives instructions on connecting the VersaSTAT 3F to the host PC and to electrochemical cell and other equipment. For operator and equipment safety, power to all instruments should be WARNING off when connecting or disconnecting cables.

  • Page 17: Connecting The Cell

    To connect the cell cable (part no. 223945) to the VersaSTAT 3F: 1) Make sure the POWER switch is off. 2) Match and attach the D connector side of the Cell cable to the front of the VersaSTAT 3F and secure the screws on either side.

    224183_0C / 082021 VersaSTAT 3F Hardware Manual If the cell has low impedance (battery) and/or the experiment generates NOTE currents more than 100mA, do not connect the leads into one another for a two-terminal connection. Instead, connect the leads independent of one another to their proper terminal at the cell to prevent voltage offsets that can result from milliohms of contact resistance in a “piggy-back”...

  • Page 19: Floating Operation

    In floating mode, the internal ground of the VersaSTAT 3F (as well as the cell leads and external connections at the rear panel) is allowed to float with respect to earth ground which allows it to operate with these grounded cells.

  • Page 20: Setting Operation Modes Of Float And Normal

    It is recommended that after one changes modes, a new calibration for DC accuracy be performed by selecting the “Calibrate Now” button above the Floating Settings option. In addition to the mode selections, the VersaSTAT 3F also provides additional filters that could be required with some cells to enhance the signal to noise.
