5. AVAILABLE OPTIONS 
The factory installed options available for the PARSTAT 4000 are as follows: 
1)  Advanced Auxiliary Interface (4 x 12-bit +/-10V inputs) 
2)  20A Current booster Option. 
3)  VersaSTAT LC Ultra Low Current Option 
 
5.1 Advanced Auxiliary Interface Option 
 
The Advanced Auxiliary Interface (AAI) Option allows for an additional four (4) A/D 
inputs for the VersaStudio software to acquire along with data recorded directly from the 
PARSTAT 4000. 
 
The AAI is an external unit that plugs directly into the same PC as that interfaced by the 
PARSTAT 4000 into an available USB port.  The VersaStudio auto-detects the AAI, and 
collects data on the additional four A/D inputs along with data directly from the hardware 
(E, I, AUX, etc.).   
 
The AAI is a +/-10V DC input, 12-bit unit (+/-5mV resolution) system, and is 
recommended for when several variables need to be colleted concurrently with the 
electrochemical data, such a pH, temperature, etc. 
 
Although an external unit, the AAI requires that 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 of necessary 
components internal to the hardware. 
 
5.2 Power Booster Options 
 
The Current Booster Options for the PARSTAT 4000 is a 20V/20A.   
 
Note: The voltage component for the boosters is compliance voltage increase, not 
reference voltage increase.  The maximum reference voltage (applied voltage) remains 
at +/-10V. 
 
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.  When set to “Booster” mode and 
interfaced correctly to the external power supply, currents up to the maximum for each 
option can be applied or measured.  The VersaStudio software auto-detects the booster 
mode, and automatically sets the parameters needed to operate correctly in that mode.
