    PARSTAT 4000 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: General

    PARSTAT 4000 Hardware Manual 1. INTRODUCTION The PARSTAT 4000 (Figure 1), teamed with the VersaStudio software package, comprises a simple-to-use, flexible, and extremely powerful system for performing a wide range of electrochemical testing. The PARSTAT 4000 is a potentiostat/galvanostat with frequency response analyzer (FRA) contained in a single unit.

    1.2.1. Potentiostatic mode In this mode, the PARSTAT 4000 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 + 48 V compliance of the control amplifier) to establish the desired working potential.

    Figure 2. Potentiostat-Mode Block Diagram 1.2.2. Galvanostatic mode In galvanostatic operation, the PARSTAT 4000 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 + 48 V compliance of the control amplifier) to establish the desired cell current.

    C) or any of the onboard ventilation fans stops working. 2.2.2. Radio Frequency Interference In a typical application, it is unlikely that the PARSTAT 4000 will act as a source of noticeable RF interference. However, when operated near particularly sensitive equipment, interference from the PARSTAT 4000 could be a problem.

  • Page 13: Transient Sensitivity

    PARSTAT 4000 Hardware Manual Once the instrument is completely surrounded by the shield (taking care not to unduly restrict ventilation), the only additional requirement is to install low-pass filters where lines pass through the shield (all openings through the shield should be as small as possible).
  • Page 14 PARSTAT 4000 Hardware Manual Such transients almost always enter the instrument via the line cord. Possible sources include heavy-duty electric motors, RF equipment, diathermy machines, arc welder, spark chambers, and others. Lightning Transients caused by lightning almost always enter the instrument via the line cord.

    Each current booster includes an external power supply interfaced to additional internal circuitry of the PARSTAT 4000 system via the rear panel. Once connected, the system can be operated in either boosted mode or normal mode depending on a switch setting at the rear panel, as well as some cell cable changes.

    PARSTAT 4000 Hardware Manual Note: In boosted mode, the system is required to stay on a single current range, and is limited in this mode to current measurements at a resolution of 16 bits for the boosted range. This option has components that are built into the base unit, so it must be purchased at the same time along with the base unit, or at a later time by returning the base unit to a qualified Princeton Applied Research Service Center for installation and calibration.
